I plan on adding an "Individual String Ports" option like the individual string start channels, just haven't had time yet. Ran into a problem today where my minitrees where I had to use individual start channels (to account for blank nodes between strings) were uploaded to 3 ports instead of one. There is definitely work to be done around the entire Controller Connection stuff. The Pi/BBB stuff is much further along (uses virtual strings for example ) with the Falcon upload not too far behind.
