GRIB2 file defined from upper left corner

Hello all. I'm a beginner with WRF and need to run a case where my GRIB2 input met data (JMA MSM) files are defined with the (i,j)=(1,1) at the upper left corner. However, it seems that metgrid assumes (i,j)=(1,1) is at the lower left corner. Is there any way around this with an input option in namelist.wps (I couldn't find info on this in the tutorials)? Otherwise I'll get to learning how to edit my GRIB2 files to fix them.

Thank you,
