in detail, you could use the Favorites to save preferred rhythms in permanent flash memory. You have 36 slots on 4 pages with bank naming to enable advance previewing the next rhythm while you are still playing. These settings can be saved to SD on their own, and will only take a second to load.

Alternatively prepare the 13 banks of panel memory with your most used pattern+registration setups including naming all bank and memory descriptions to identify them and save just panel memory set to ALL to SD. Load at beginning of set, now while still playing you can scroll panel memory bank view page 3 or 2 to advance preview the upcoming setup you require by pressing the bank button. The 104 memories should be enough for a set, considering the next 104 will only take one second to load from SD, while you sip a drink or say a thankyou. If you save both the ALL panel memory banks and the Favorites together they will still only take a second to load the next batch of multiple banks of setups.

By using both you can play full registrations in the panel memories and preview the next full setup in advance while continuing to play using the panel memory bank or memory view... or preview the next change in rhythm only in advance without changing the right hand sounds while playing by using the favorites. Or you could filter the rhythm selection out of the panel memory registrations, just using them for right hand registrations keeping the last rhythm selected until you change it with the favorites.
