Hello Alexander!
The short answer to your question is “Not natively, but…”!
There have been a number of posts about similar requests, so Blokas might have it on a list of improvements for a future update.
This topic covers two patches related to Program Changes with links to patchstorage.
The second patch does the incrementing/decrementing I think you’re looking for. Would need adapting if you want to use a key-press.

Also, there is this patch which can be adapted to cycle up/down through up to eight presets,/programsetc.
Probably not useful for you Alexander; I mention it for future readers who might not need 128 “states”.
For them, I’d recommend it over the others because it needs no physical-loopback.
