P: Lock Lightroom masks

Ability to lock Lightroom masks to avoid accidently activitaing or altering one. I often find that I have several masks and while working on one I inadvertantly trigger a different mask and sometimes move it, or unintenionally alter it.  A lock icon inbetween ot the "three dots" and visibility icon (the eye) would be very very useful and helpful. Easy access to trigger it and turn it off. I believe it would be an extremely useful feature.......
