Config / G92

Probably a simple very simple question but can’t figure it out.

I have a few printers and currently have a few different profiles in Simplify3D just for the starting script to set the Z height using G92.

G28 
G92 Z238.30

I was told I could just add it into the config in each printer which would save me from having to update a bunch of profiles every time I change anything.

Thanks.

See the 3D printer guide,and the documentation page on endstops, there are several ways to do this in config.
Is this a delta ? Is it homing to the top instead of the bottom ?
