P: (Masking) Let us select and move several masks at the same time

I've made a fake light leak in Lightroom using masks. To get it looking as good as I can, I had to use several masks and several modifications (additions and subtractions) on each mask. 

But now I can't move the intended effect around without moving each maks and each piece of each mask separately. Which makes putting them all in a different location in the photo, hard. It's hard because there are many things to move, meaning many tasks to do, and it's hard because it's hard to line things up the way I originally intended. 

So it would be nice to be able to select several things and move them at the same time.
