RC control flight mode switch using stick issue

Hi fellas, I am a beginner to the drone, I use a transmitter stick to switch between different flight modes, I have one question that is when I assign two flight modes, such as takeoff and hovering mode, once I engage one mode, can I use another stick to switch to a different mode, like return, I feel this will coz a conflict, if this will override the flight mode, how can I switch back to the mode just override?
Thank u, guys.

Each change in mode overrides the previous. No conflict, it’s the change in mode that is recognized. The sources don’t matter. I can’t picture what you are describing with stick mode changes though.
