Is there any way to set a new "home" world for a particular ship? Freighters, for example, always create a trade lane between an alien world and whichever planet constructed the ship -- is there way to, say, build a freighter on Earth and somehow convince it that it's home base is Mars? I've tried moving the freighter to Mars and re-launching it before sending it to an alien world, but that doesn't seem to do the trick....
