Why not allow PUPs to have an extra setting done with the "Gear sets" option they just added? Where you do a basic set of the attachments you most use for each head/body and then you can add different attachments to it later for the variable situations.

I don't think SE thought(or cared) too much when then added the major customizations that are done with pup and the difficulties of having to do all the attachment swaps. It's almost similar to the annoyance of setting blu magic spells.
