Linking maps

I realize there are some performance issues inherent in larger maps for BeamNG. Be cool if you “go through a tunnel” or “get on a ferry” and load your current vehicle and mission into another map.
Example: You have a semi truck cargo to haul from East Coast USA to small Island passing through Utah and West Coast. So you’d drive you course to a spot on East Coast, go through the tunnel into Utah, drive your course through there to the next point there, ditto for West Coast, and finally you’ll “get on the ferry” for small Island and make your delivery.
