I've wanted to remaster my Remington 870 Tactical for a long time now. The problem is, my original build is proportionally too small; every part needs to be scaled to a magnitude of approximately 1.25.

My query: is there any way to XML scale every part in a build with a single input? With every guide I've seen, you can only scale an individual part. I've also seen some builds that seem completely scaled up (every part seems to have been scaled in tandem), which furthers my confusion.
