Describe the solution you'd like

I printed a single layer and send a commant to lower the z offset by 0.5... 5 times... at teh end of the print I check and 'rollback' (adding the same value as positivem add an extra 0.05 for aasurance) and SAVE.... then do it again but with 0.025... now I have a great first layer.. would be nice to have a model that prints a rectacle and change the offset mutliple times and then simply pass the value that look best... similar to the YOLO flow calibration... use the CURRENT z offset maybe with .1 extra and go down by X....

Describe alternatives you've considered

mmm manually sendiong the command in mainsail works... but require me to keep looking and manually sending the command... and I cannot add custom code on the same layer :( ... im not that good editing gcode by hand either...
