I know there's something similar in Clip Studio Paint!
If you're like me who organizes colors (hair color, skin color, eye color, etc) to different layers, Clip Studio Paint has something that allows you to combine layers together without having to merge them!
So here are my layers. The one in red is the one I've highlighted. However, the ones in yellow are the ones I've checked off. The checked off layers will move whether my highlighted layer moves. Even better, when you select the certain parts you need, all of the highlighted and checked off layers move together.
So you can resize, change colors on, and move your characters without ever having to merge layers together!
