Child/Dependent Task Due Dates - Need more options

Current options - Choose X number of days after Parent Task is Completed.

Recommended Options:

• Child Task “Appears/Activates” once Parent Task is Completed; however, its due date is based on the original due date of the parent task. Ex: Let’s say Due Diligence is still technically active, but any Amendments have been signed off on and it’s essentially wrapped up. I would like to get the ‘Due Diligence ends’ task off my list, but I don’t want emails for my next phase to trigger until the Contingency Period has officially ended which may still be several days away. So, being able to choose that child task is due X Days after Task (1) Due Date or (2) Completion Date would be amazing! There are several semi-standard emails I could set to auto-send if this was the case. I think I put this in a separate request, but I would love to have the option to hide/filter out sms/email tasks that are set to auto-send. Then all of this is off my visual plate and ideally I wouldn’t have any lingering ‘past due’ tasks counting towards my numbers. Hope that makes sense!
