(Solved) Forced automatic weight paint

Add the option to assign automatic weights to your objects AFTER you've already combined them with the rig. And only apply weights for 'remaining' vertex groups (don't re-create the missing ones).

I have complex models, consisting of several objects (i.e: Body, Hair, Armor, Weapon, etc...) But I use the same rig for all of the objects. However, not every object uses all the bones from the rig. I'd like to be able to just redo the automatic weights once I'm done clearing up the unneeded vertex groups form each object. Manually correcting the weight paints is both really time consuming and the result isn't better than it would've been with automatic weights (in fact, I think it's worse).
