Aha, I seem to have figured it out!
- Open the |||\ menu.
- Create a playlist.
- Add all the presets needed.
- Make sure that playlist is selected.
- Close the menu.
- Insert Program Changes in your DAW as needed.
- Program changes are selected from the playlist as they are numbered (up to 128, I presume).
Simple (but undocumented ion the "new" manuals I downloaded yesterday).
