Continuous Add and Remove for Cryptomatte

Sometimes when using Cryptomatte the objects to isolate and divide into various passes can be a lot, and the process becomes tedious because you can only Add or Remove one object per time, then go back to the Cryptomatte node and click the + or - icon again, slowing a lot the process.

Instead, it would be way handier being able to select multiple specific objects, by having Add and Remove to work with multiple clicks, and then press Esc to go out of the selection mode when needed OR be able to do that when holding Shift after clicking the + or - icon.
