Comment 4 for bug 1630174

How about the warehouses/ports/HQs? They are logically connected to setting target quantities, and economies without one can't really be configured. Potential downside is the potential confusion between the wares stored in that particular warehouse and those in an entire economy combined.

On the other hand, I would welcome an easy way to provide a cache of goods in the warehouses where they are needed, for instance building materials on the expanding edge(s) of a large empire. Probably a different bug though. :)
