Mod Function missing- build new ports or build something can import and export, please

[foran]

Function missing- can we build new ports or build something can import and export as a major in next version, please.
Otherwise, it's very weird!
After that, airport can become one of the way to import and export, also can be build in after next version, please.
I'm looking forward can build new ports very much, and I'm sure there's a lots of players want the same.
Thanks a lot.
