It just got added in 2023, but there's now --auto-tune-dump which generates a command line invocation of powertop that would set all the auto-tune settings. Instead of running --auto-tune, you can make a script of this dump, modify it to your contentment, and run the script instead of auto-tune at startup. So you can omit your mouse!

Ideally there would also be a way to omit certain device or subsystem tunings from auto-tune as well.

Personally I think it'd be fun to mess around with more advanced schemes, where we dynamically alter powersaving behaviors based on user behavior. What we have now seems somewhat unresponsive. It'd be fun to dive into.

Awesome! Yes, I was thinking about doing this manually by toggling every setting manually and copying the command being displayed but gave up quite quickly as it was too cumbersome. Sometimes the screen would refresh before you copied so you had to do it again... This option solves that nicely.
