Could you add a couple items that can potentially upgrade backpacks and other player wearable containers similar to how our most recent system allows us to craft kits to upgrade static containers?
We can use tailoring level as a way to limit each tier, and each tier gives a little extra storage/weight reduction.

I realized this mod already does so much with containers, and this mod https://gtm.steamproxy.vip/sharedfiles/filedetails/?id=2996978365 that was supposed to have this feature no longer works. Just wondering if that could be an extra addon to the "Customizable Containers" mod. Cheers!
