Pretty sure they are using switching jacks that interrupt the signal to the mains section as soon as a cable is plugged in, so there is no hope of a future software update that addresses a different routing possibility. If you notice, the the voices rob the headphone out as well, which was my biggest clue. Personally, I'm happy to have the direct out of each voice available bypassing any software mixing or onboard effects, as I have much better distortion and compression available outboard. They are nice to have when I'm not tethered into the studio though, for quick ideas.
