Use conditional logic to set due dates

Dynamic due dates may change based on the conditional logic showing and hiding tasks. to avoid having to duplicate tasks for each outcome, it would be great to be able to set the due date of a future task based on which tasks appear as a result of the conditional rules eg: If Task A control = 1, Task B is shown. Due date of Task C is 3 days after Task B is completed. If Task A control = 2, Task B is hidden and Task D is shown. Due date of Task C should then be 3 days after Task D is completed.
