Just add an npc function aka the rough lusterious stones.

go to npc, exchange, click 'sack of' whatever, and trade them in, game gives you resulting items (It can calculate what each sack gives far faster than it takes us to click them or spam the hotkey)

This was not really a well thought out thing they added. ALso, please don't just make them dump the matts into storages, this would make many peoples storages go into overflow, which would stop all workers from that town.

MORE IMPORTANT LUMBERING SACK. It is clogging up more storages than anything else.
