how to keep settings of some applications?

I'm new to this, I want to know how it is possible to keep the native options of some app (for example notes), but that when I go to the desktop, the global settings are created?

When you add a new app specific group using the plus button at the bottom left you can chose what you want to display (macOS control strip, BTT, app specific actions,...) for this app only.

Can you rearrange & mix in items from BTT & native?
