Lockable Custom Layer / User Management

I didn’t find this already posted - I apologize if I overlooked something.

I often use the unit to set up small events, e.g. weddings or corporate stuff where I’m not present during the actual event. Typically, I create a custom layer with the channels required for that event so levels can be adjusted by the customer if required.

It would be an ideal fool-proofing measure if I were able to lock the screen on one of the custom layers so no one can change Config, processing etc.
Of course, a full-fledged user management would also do the trick.

I’m interested if such a feature would be helpful to others as well. If there are other ways to achieve my goal, please let me know.

Best regards from Germany
