When there are multiple billable items that get added to an invoice, moving each item under a bundle item takes considerable time. Sometimes there are over a hundred lines. It would be nice to be able to "select all" and move all the selected items under a bundle as a mass instead of one by one. Other factors that make moving one by one frustrating is that there is a delay in the mouse movement vs what is displayed and if you don't place the item just in the right spot it fails to move.
