"any random system that is independent"
Well, the title description pretty much says it all. My TC/plug-in I am working on has 20 independent systems that are not part of any major government. I want to set up Ferry Passenger to <DST> generic missions from one independent system to the next. But I can't figure out how to do this. I can't just use -1, because I don't want these missions to be available from any of my government controlled systems. Am I just stupid, and missing something obvious?
