How to set X-Y point for "Automatic Thickness Measurement"?

Hi Makers,

maybe a trivial question, but how can I set/control the X-Y point for automatic measuring of the material thickness?

For me it seems that most of the time (but not always?) the platform center is used.
This might be reasonable in most cases, but of course it is not if you have mounted the material somewhere else on the platform.
Also the step for setting the work origin comes after thickness measurement, so I wonder how the snapmaker should know where the material might be mounted…

Thanks a lot for your answers!
