Copying a comment I made as I'm rather happy with it and think it's a solid idea
rework the item system so when material selectors like iso or class cats are given in volumes larger then 1 we could have a further volume selector for those materials
For example, when selecting how many of class cat selector for glory I can pick 1 to 10, that volume selector should then be in that class cat nexus window under each class so I can pick 3 of mystics, 2 mutants, 5 cosmics, in 1 window instead of 10 tedious windows.

@KabamPinwheelAcross the board, all sorts of selectors like need need fixing, some QoL baby
