Homing Z from LCD Needed

I wish there is a way to do Homing of Z from the GLCD panel (without a computer hookup).
One of the more often done things in using TAZ is the adjustment of gap space between build platform and tip of nozzle. It will be really nice to be able to do this without having to use PRONTERFACE or a computer.

There is the “auto home” option, but this does x,y, and z. I usually “auto home” and then “disable steppers” and then go from there.
