Im afraid while id love to add some sort of system like this, we would have to put a large portion of time into this project which we just dont have right now.
Cant think of any logical way to do this without coding an entire new bodygroup addon system which just seems not worth it for such a change, maybe im wrong tho.
You got it wrong man lmao, nothing to do with bodygroups its now that most jobs are now limited to 2 models max, also all branch models must follow a set design and halo pink,blue,green models dont so they got removed, thats why.
