Formula inside a single QM Inspection Characteristic

Hi all, is it possible to have a formula that will find the difference  for measurement nbr 2 minus measurement nbr 1, measurement nbr 3 minus measurement nbr 1, measurement nbr 4 minus measurement nbr 1, etc. in a single inspection characteristic?

If the measurements are .003, .004, .006, .003,  the frmula should be .004 - .003, .006 - .003, and .003 -.003.

Any feedback or reply will be greatly appreciated.

Thanks, Aida de Jesus
