This also would allow you to sell trade goods in a town far away, without transporting them. eg. you are in Valencia and open the storage of Grana with your maid to get the trade goods you stored there and sell them with a massive bouns in valencia. This is not how it should be, so it will never happen.
I would at least like to be able to select none major cities I am in range of. My stuff needs to go to Keplan per say and maid only finds Calp storage.
