Add a top connection on pipes.

If i have a connection and want to add a connection it is not posible to do it vertical the connection will always be horozontally.
I have the tendency to build on a small spot. effectiveness is key :-).
With al the pipes crossing it would be a great win to make a 1m by 1m box pipe with connections on all the sides. up down left right front and back.

Or, if this is not implemented, remove the little circle on top which looks way too much like a pipe connection!
