Found this thread and it’s exactly what I need. Very disappointed that it’s been years without official update on if it’s coming. This is a fundamental workback concept, a parent task has a due date, and then you work backwards from that due date to ensure you have enough time to complete all the subtasks ---

Hi Rebecca, any updates on this feature? Seems like it should be available for paid Asana customers. ---

I would really like rules that update based on a due date dynamically. What do I mean? Here’s an example: If I have a monthly recurring task due on 12/1/25 and a rule creates subtasks with due dates 1 week prior, if I change the due date of the parent task let’s say I move it to 12/15/25, the due dates of the subtask do not update and are still due 1 week before the original date 12/1/25 (instead of 1 week before 12/15/25). This limits the functionality of rules creating subtasks with due dates. ---

@Carrie_Morales - I’ve merged your post into a similar request thread. Consider giving it a vote! Additionally, you could consider voting for this other thread (basically the inverse of what you’re asking for: subtask dates → update parent task date): > [@Connect the due dates of subtasks to the due date of their parent task](https://forum.asana.com/t/connect-the-due-dates-of-subtasks-to-the-due-date-of-their-parent-task/12153): > > Hey there. I am trying to set up a project in Asana to function as a workflow for a blog calendar. I set up a task that represents all the actions that have to happen for a blogpost to be published. I then set up subtasks (12) for all those actions, set up the appropriate dates and set up the dependencies as they need to be. My plan was to copy this Task for each blog post and adjust the date. However, when I change one date, the rest of the dependent dates do not adjust their time. Since I can… ---

Ah! This is amazing. I think it should automatically be updated whehter you update parent task due date or subtask due date. Or be an option. Thanks for directing/merging me to the post!! ---

I had the same requests, subtask due dates to flow down from the main due date. It can work in the same way you set up automated dates based on task creation. This is very important and would make all of us much more efficient. You can set a main due date and all the subtasks are populated based on the template parameters. ---

I am absolutely staggered that this isn’t an option. I did’t even think to check, I saw you could set rleative due dates, it never occured to me that they would be limited to only after the task date!. You can only set relative due dates in a task template AFTER the event. How does that make any sense in a supposedly mature PM tool? Who preps for an event after the event? It doesn’t make any sense. Has anyone found any workarounds for this? We do a bunch of webinars, they have the same pattern of promotion and tasks associated with them. I just want to be able to drop the template task on the date of the webinar and the subtasks backfill into a promotional and task calendar. I absolutely can’t believe that this basic planning function can’t be done with the amount this costs. So disillusioned! ---

don’t you have to pay additionally for flowsana? this feature should be built into the main asana software instead of having to use an additional app for the feature. ---

@Gina_Peter1, Yes, that’s correct, we are a separate paid 3rd party integration. No argument that it should be built in, but unless/until it is, we are here with a solution. ---

Creating a due date based on the day the task is created is utterly worthless. We create tasks from templates months before they are due and never consistently the same amount of time before the due date. Setting relative due dates on subtasks based on the due date of the main task is a fundamental workflow function that we shouldn’t need an external integration that we would have to pay extra for to accomplish. I’m flabbergasted that this has been requested for years, and it still isn’t available. This is a basic and highly desired feature. Why has nothing been done? Even Flowsana agrees, “No argument that it should be built in.” ---

When I update a task’s Due Date, I would like its subtasks to be updated to match the Due Date of the parent task. I tried to do this with Rules, but according to the AI Chat in Rules, “Asana rules can only modify the task that triggers the rule.”. Having the ability to change subtask Due Dates via Rules would be very helpful in managing projects. I do not want to subscribe to a separate service to handle this use case. ---

This is not possible with rules indeed, and this isn’t a behaviour everyone wants. So either Asana improves the rules, or make it an optional behaviour. It has been like that forever, but we know Asana is working on subtasks! ---
