The Supply Zone

[Sion]

This is a new zone, The Supply Zone, it works just like the other zones, that you can specify the size and what's allowed ti be in the zone, but this zone has one exception, it can be selected from the bills of the different working tables, like Butcher table, The Stove, Stone cutting table, and so on.

Why?
Instead of setting a radius that can overlap with some other stockpile that you don't want it to interact with, you can simply say: "Take stuff from exactly this zone, and ignore everything else, even if the zone happens to be on the other side of the map".

Why can't the already existing zones work like this?
They could, and I think it would be preferred over needing to keep track of another zone type, but it might be easier to program an new zone than modify the already existing ones, I don't know.
