I’m looking for the best way and feedback/work arounds to solve for: 1. Auto populate the due date of a parent task based off the last subtask. Currently isn’t working and the last subtask IS a dependency blocking the parent task 2. Task templates appear to NOT have the capability to use anything other than the task creation date for the due dates of subtasks and the subtask rule has a limitation of 20 subtasks per rule logic and then the last subtask in each is unable to be a dependency for the first subtask in the next group of subtasks. 3. Shift FORWARD due dates as dependent subtasks are completed. Goal is to have 38 subtasks added to a parent task with due dates being based off various SLAs and assignees. ---

For #2, see: > [@Subtask Due Dates Relative to Parent Task’s Due Date in Templates](https://forum.asana.com/t/subtask-due-dates-relative-to-parent-task-s-due-date-in-templates/1045133/2): > > Welcome, @Gaby13, You can’t do this with task templates, but you can do this with rules, and usually a rule like this can do most of what a task template can do, though not always all: Thanks, Larry which might help there. Maybe someone else will help with the rest, which for me is usually better handled interactively. Thanks, Larry
