I've not used Jukebox like this with only initial data being sent.
As a work-around:
I'd add a 100 measure muted click. This will allow time to pass and you can simply click stop (or use a pedal to stop) then advance to the next song.

When I've used PT for patch changes in live setting, there were often a few changes in a song, so to me it was important to have the song actually run from PT/RB.
The amount of added data or stress to the system would be minimal.

I do not work here, but the benefits are still awesome
