"Shift" planned completion date of multiple tasks by X amount of days

[#1]

We frequently need to shift a large number of tasks out by a week or a month, based on client needs. Right now, we have to move out every, single, task, one-by-one and we don't think we should have to.

WorkFront support confirmed there is no way to do this right now. Here is one proposed solution:

1. Select multiple tasks
2. Right-click > Shift dates... (just like bulk edit, but shift dates instead)
3. Pop up asking if you like to move dates to left or to right and # of days.
