I’d also suggest considering switching out of bank mode to performance mode (tap upper left dial) when needed, and set up a hot switch to go between the different settings in the same pair of algorithms (i.e., stay in the same program).

I do a similar thing: each song has its own bank, and the three programs within the bank are the different parts of the song, but with some songs requiring going into performance mode for some parts. It’s just one more click and doesn’t require extra hardware.

As one of the people who has struggled with the brief drop out (or lag) when switching between programs, it’s worth exploring alternatives to switching programs for each part. Anecdotally (I haven’t measured it), the lag/drop out seems to have lessened with the newer firmware updates.
