Bulk update activities on the weekplan --> "move selected activities by x days"

In order to be closer to lean construction workflows, it would be very helpful to be able to move a selection of activities on the weekplan not only by selecting a new start or end date but also by a certain amount of days back or forth. Reason: In a lean takt plan, activities of a certain kind are staggered and I want to be able to move them all together by a certain amount of days which means they will not have the same start or end date before and after. Please see screenshot.
