In Create, it is a fantastic feature to be able to go out to another deck and select a slide that already exists. What would be even more fantastic is if you could select multiple slides at one time instead of having to go back to the previous deck multiple times. This would be a timesaver and reduce frustration.
I second this idea. I use a lot of pages from other courses to build out new courses. It would save an immense amount of time to be able to move more than one page at a time.
