Mapping a keyboard short cut to 'Protect Library' on and off.

Does anyone know if I can map a keyboard short cut to 'Protect Library on or off "? I looked at the actions we can map in Rekordbox 5.8 Settings.

Can this work with MIDI mapping ? (I got a DDJ-1000) ? (never done it)... sorry, I'm new to Rkbox ! :)

An improvement of the PL feature is in Pioneer's 'to do list' since 2 years and it drives me mad as deleting metadata is too easily done (hyper key sensitivity upon double clicking on a line which is a very common move). So in the meantime, I'm looking for plan Bs to compensate. Thanks.
