Does the Jukebox feature change registrations, too, or just SMFs?

This is a limitation on Roland's I've been requesting them to change... They've got a great jukebox feature too (called the Set List) but it only loads and plays SMFs, whereas it would be MUCH more useful if it loaded and played UPGs (registrations) with Linked SMFs, as the UPG nowadays tends to take care of the keyboard Tones and splits, etc.. Just changing the SMF doesn't do this (although, with a workaround, you CAN get it to call up the Tones, but other things like split points, key touch etc. require a UPG change)....
