Awesome - thanks for confirming!
I managed to get up and running pretty quickly in the end. tapping the probe seemed to take some effort to activate the LED and I wondered if it was just going to bash holes in my printbite during probing, but it works and amazingly well.
nice to know there is that possibility for MOD , I'll implement it when I come to another good reason to take the bed up , the default is fine for now.
And the probe is a totally brilliant solution, I cant get over being done with effector tilt and changing z offsets, measuring all the points again.
