Not sure if this belongs here or into cosmetic requests. Apologies if it's the other.
Whenever I apply camouflage to guns I prefer painting only the receiver itself and none of the attached accessories, since it makes the gun look less like I dipped it into a paint bucket. Unfortunately this means whenever I have to do this I have to set a preset and then individually re-paint every single part of the gun so that only the receiver, the main body of the gun, has the preferred paint.
I think it would make for a good quality of life choice if there was a button that lets us only change the receiver paint. That way in this example, changing only a receiver and leaving everything else in a base color, would require only 2 paint changes instead of 8.
