As an example, I have a task with a certain due date. The subtasks all have that same due date. If I want to change the due date for not only the task but also all of the subtasks is there a way I can do that?

(I know I could change the date for the task, click the box at the top of the subtasks to select them all, and make that change in mass. I would like to roll both steps into one.)

The real advantage would come when I have quite a few tasks with their subtasks and would like to move the quote a few tasks and their subtasks down the road. Changing the date on all of the needed tasks in mass is easy. If there was the ability for the change to also apply to their subtasks, that would be ideal and much quicker.
