Allow the Create Subtasks rule action to create subtask due dates that fall BEFORE the parent's due date

[Emily_Kokol-Rivera1]

I work with multiple creative teams where it would be most useful to be able to set the due date of the parent task and have subtasks automatically created that lead up to the parent task’s due date. Right now that doesn’t appear possible within the rules builder. Am I missing how to do this or is this not available? Thanks!
