A perk to craftworks that lets you set a limit for production of a certain item, for example say you want 1000 tables and 1000 wooden planks, it will craft plank then tables but stop making tables once the current stock is 1000 and start ac-blam!-ulating wooden planks till the limit of 1000 is reached.
This could be a gold perk aimed for mid-late game or it could be part of a questline requiring an item, maybe the processing core of a broken robot that can not be repaired.
