Is it possible to limit the type of weapon that an upgrade can be used in by editing the upgrade itself, rather than altering the weapon's Upgrade Level?

I am working on a mod for my game to make the weapons more balanced (and hopefully "realistic"). So, I was wanting to make Level 3 chamber/power supplies off limits for pistols and carbines.

I can work around this by giving each pistol an upgrade level of 2 (scope/chamber) and then editing the baseitems to give pistols and rifles the relative damage capabilities I am looking for, but I was really hoping there was a way to limit upgrades to specific weapon types.

Editing properties won't work. Perhaps the kgff editor? I opened a few files and looked around, but wasn't sure if there was anything I could change to get what I want.

Any suggestions?
