Add option to show only perm guns in storage

So with my latest bm crate run I won deagle camo and xm8 adv, and I tries for deagle scope but didint win, but from all the crates now I've got like 10 tepm guns, some 100 days+ and they are colgging up my storage, most of them are ones I don't even wana use, some of them I have temp is micro galil, colt 1911, mp7, all the bad guns, so I'd like to be able to only see my perm guns in storage, that would be awesome.
