Requesting the means for pack-devs to be able to add custom entries into the existing "kinds" for use with the strife specibus for example, making the support and integration of features a lot more flexible. I.e. say I wanted to have techguns guns in gunkind to have available to swap between in said specibus.
I'm not too particularly familiar with the source material or if theres any mechanics implemented with certain kinds that would make such a quality of life feature untenable within the scope of this mod , or if this is something that should be addressed with the base mod.

The source material never really gives any details about the mechanics of how strife portfolios work, beyond establishing that you can switch weapons freely, and that you can't re-allocate a card once it's been allocated (though when John's hammer breaks, his Hammerkind card changes to Stickkind for no particular reason, and Dave's Swordkind turns to 1/2Swordkind when he breaks an incredibly dumb and awful katana that he definitely wasn't praising a couple of pages earlier).

Some fanon exists, but it's fanon, and therefore doesn't necessarily apply.
