New building. Some kind of "mini HQ": collects resources from nearest buildings. If you have some massive resource production far away from HQ, spend 1 claim to make shipping faster and cheaper.

Some variants:

1. Collected resources bacome available in all hubs/HQs (as if it were another HQ).

2. Transport hub sends resources to nearest HQ, but uses advansed transport: bigger, carry multiple cargo types, faster, uses less fuel, defensed against pirates.

P.S. How about special lab for transport improvement instead teleportation?
