Custom Ports

Anybody think it would be nice that you could place an im-/export anywhere on the building walls?
So say you have a production line, but no where to export to because everything is blocked, or you have a large room with only two ports or you have an uneven number of ports.

Restrictions on this I feel should be:

  • It has to be researched
  • It costs a ton of money, as you are basically retrofitting a building
  • There should be a set limit for the number of ports per building. That means that you cant have 60 ports, but say only 15 (including the ones already installed.)
