Replace default buttons for sounds?

As I’m starting to customize sounds for playing live, I’m adding presets that I’d really love to tie specifically to the buttons - I don’t want to replace the Jazz B3, for example, but I do want the organ button to point to my own preset. I cannot figure out how to do this and the documentation doesn’t seem to indicate that I can (or maybe I’m missing something there). Has anybody figured this out?

At this time, there’s no option to customize the default presets for the Type buttons.
But you can create a Playlist with your favorite preset for each Type button (or multiple playlists/songs with various selections of presets).
