Describe the Task

I would like to add an example to the users' guide for the pcp_combine -subtract option with a list of files. I just used it for the first time and I could not get the syntax right until I found it way down in dtcenter/METplus#1138. All of the current examples in the users’ guide are either for -sum or else only have one file involved instead of a list. Something like:
pcp_combine -subtract 2022043018_48.grib2 'name="APCP"; level="A48";' 2022043018_36.grib2 'name="APCP"; level="A36";' sample_fcst.nc
