Something to make posing with ragmover in vehicles/other models easier?

[v0lus]

I need something that can "hide" a model/prop, so that I can pose ragdolls using ragdoll mover inside it easily, because now trying to pose ragdolls in other objects is a nightmare. Is there an addon, or something I can do? by "hide" I don't mean totally invisible, just something so the physgun and hopefully other tools don't interact with it and goes THROUGH the model.
