G12: Clean Tool need some help.

Hi.

My printer is a home built cartesian style with Z moving up and down.
I have added a steel brush on one side of the frame to clean the nozzle on.

In my start up script I have G12 P0 S6 = works great
NOZZLE_CLEAN_PARK is enabled.

But I want to clean the nozzle let say every fifth layer also.
Now it moves Z to 0 when it cleans the nozzle then back to the active layers Z position.
Not good on a printer that moves Z up and down

I think the problem is the variable Z_MIN_POS within the G12 command in configuration.h.

Could it be possible to make a variable defined as Z_CURRENT taking the current Z position and store it?

Or any other idea to avoid that the G12 command moves the build platform in Z?
