Subtask relative due dates based on parent task start/completion date

Please allow updating subtask due dates based on the parent task’s start or completion date. Currently, the only relative due date option is based on task creation date. What if I am adding a task today to be started next week?


Hi @anon93576813,

You might want to take a look at the “Add Subtasks” rule action in our Flowsana integration; it allows you to do exactly what you’re asking for. :slight_smile:


Hi @anon93576813, thanks for providing this feedback!

While this feature isn’t available right now, hopefully it’s something our Product team can implement in the future.

I’ll keep you posted and let you know if we have any updates :slight_smile:


There should be a way of choosing a due date for a task template and having all of its subtasks adjust their dates in relation to that.

For example, I need to create a monthly marketing update. This involves several subtasks assigned to other people. Perfect use case for a task template.

Right now, due dates are set relative to when the task was created (from the template).

Instead, I’d like to choose the due date when creating the task (e.g. the 2nd Monday of the month) and have all of its subtasks adjust their due dates accordingly (e.g. to be due three days before that).


Yes! This would be very helpful.

We almost always have to select very specific dates for when a parent task is due (for example a product launch). Automatically setting the due date a certain number of days from when the task is created doesn’t make sense. On the other hand, it would be very helpful to have subtask dates relative to the chosen due date of the parent task.

I guess in order to add this functionality you would have to force someone to choose a due date for the main task if they’re using a task template that has relative dates for the subtasks. But that is well worth it. Unfortunately relative due dates aren’t useable for us as it’s currently set up.


FYI the “Add subtasks” rule action in our Flowsana integration has this feature - you can have the dates of subtasks be set relative to the due date of the parent task.

Have there been any updates relative to this, without having to integrate another program? While we could add Flowsana, we’re already overwhelmed with too many apps/programs, and don’t want to continually add new apps for individual functions.


Hi, Phil - the first link is broken.

I enabled Flowsana, but see nothing in Asana. How do I find it?

Hi @Silvia_Mioc,

Thanks for catching that link issue - we recently moved to a new support system; that link should have forwarded to it but there was a configuration issue, now fixed. So please follow that link for info on the “Add subtasks” rule action.

You can build Flowsana workflows, like that rule action, from the Flowsana web portal. If you have an Asana Business or Enterprise subscription and thus have access to custom rules in Asana, you can also incorporate Flowsana rule actions into your custom rules in the Asana rule builder.

Thank you.

I am on the premium Asana trial, just joined today. I’m evaluating using it just for my personal project organization, not for a team.

Is the Flowsana available to me? I could not find it anywhere in my Asana after giving it all the permissions requested.

If it is, how do i access it?

Thanks for your help!


You’ll create your Flowsana workflows in the Flowsana web portal. Once a workflow is created there, Flowsana then watches your Asana data and automatically runs the workflow as appropriate on your Asana data.

It would be great if it were possible to create a rule that triggers a sub task’s due date to be a certain number of days BEFORE the parent task’s due date.

As far as I can see, it is only possible to set the due date based on the trigger time, start date of the task, creation time, and due date (i.e. number of days AFTER the due date of the trigger task).

Welcome to the Asana Community Forum @Alison_Shannon :wave:

I think this existing feedback request thread is what you are looking for?

Also I recommend having a look into Flowsana.

Upvoting this! It’s great that subtasks can get dates assigned automatically but doesn’t help that we still have to adjust the date based on the parent’s due date.


Yes this would be so helpful. I am not sure why the current feature is set to task create date and not the due date. That would make more sense.


@Rebecca_McGrath @Phil_Seeman please please please help make this happen. It is an incredible amount of manuel work when we have tasks for every comm in a campaign and then the campaign gets delayed and we need to update hundreds of subtasks. This is such a basic function we shouldn’t need a external integration to make it happen.


Hi @Bradley_Damman,

Make sure you vote for this request at the top of the thread if you haven’t yet!

(FYI Rebecca is no longer with Asana, and I’m the developer of the Flowsana external integration, not an Asana employee, so I can’t do anything to make it happen within Asana itself…)

Has there been an update on this function? I am having the same issue where I use Asana to manage my campaign deployments and I have a parent task due date, but with a lot of subtasks with their own due dates. Typically they are a month prior to parent task due date etc.

It would be awesome if we can just update the parent due date, then all the subtasks update accordingly based on the timeline you set for them.
