Saving a mask?

Hey guys, I’m trying to find a way to save a mask (by that I mean being able to reactivate a mask in the same place, with the same form as before).

Has any of you been able to do this? I was hoping that it could be achieved with layers but It doesn’t seem to be possible…or is it?

You can’t do that, maybe later I’ll ask masking to the layers.

I need to think about the whole UX,


That would be great, thanks!
