Would it be possible to let the Limited Barrel III stack size be changed so that the bottom two drawers are a quarter the size of the Limited Barrel I, while the top drawer is half the size of the Limited Barrel I? (picture as proof of concept)

The only issue with this currently would be an incompatibility with the compacting upgrade, but considering that the drawers with that upgrade still have their own pseudo storage I think it would still work.

I will think about this though this would further complicate how stack sizes are calculated so at this point I feel that I don't want to implement it, but if there's an easy way to change the limits I will likely add it.
