I really really need to make some toggles, like "mouth opened" "mouth closed" work on, for example, only on costume 5, not globally. What I am trying to do is to make the characters body disappear on "mouth closed" so I could switch it with other model and show it back again on "mouth opened". I can do that, but doing so results in main characters body being toggled on all costume layers

In other words now I need to rig the same model from scratch again in exactly the same way, origin to origin, to have the same effect.
