I would request that you would add or allow us to create rules based on subtasks.
For example in a project flow - I have a task that contains multiple sub-tasks. This task is connected to my editorial calendar and the due date on the task is based on when it will post, but I would like to create rules for my subtasks. So as I change the status of the task it can automatically change the due dates on the sub-tasks. Right now I have to manually do this and it is quite time-consuming.
I could create tasks that are larger but having one task house my sub-tasks is a much more organized method.
