Hello,

I’d love to be able to create a rule that automatically sets the due date/start date of a task based on an effort field (like workload uses) whenever either date is changed. For example, I’d want to set a “Weeks” custom number field to 1, and if I set the Start date to July 1st, it would automatically set the due date to July 8th. If I then changed the due date to July 10th, it would change the start date to July 3rd. The rule entry could have a dropdown that would say what the unit is (hours/days/weeks/months etc).

Thanks!

Henry
