Please bring back the right click "Insert all slides" feature in Powerpoints Reuse Slides dialogue
After opening the reuse slides window and selecting a powerpoint file from which you wanted to import slides, you could right click on one of the slides and see a "insert all slides" option. This allowed you to insert all the slides from the other file. Please bring that back. Selecting one slide at a time is a long arduous and error prone task for those who reuse slides often. I cannot see any benefit to making it go away and a great benefit for keeping it.
