Wow. Didn't know you could do that. Thanks for sharing. I prefer the script, but will use this as a way to select ALL common parts-- sorta like a cheap man's hierarchy tool where you can name each set of parts with a prefix and then select the correct groups.

I was wanting to create a mannequin for positioning in MoI but didn't have a good way to control easily many groups at once. This technique should do the trick!
