Will there be medium and small options?

Is bigger

I based the capacity off the default aggregate storage and the open storage that's available in the Sea cargo port mod. That one is 9450 tons and its bigger than this one. I don't plan on any updates to this mod, as I just put down 8 of them for my port in my main save. You are free to edit the building.ini to any capacity you wish.

Large Bulding, and have small capacity.
