Modifying grib2 files

Hello!
My aim is to run WRF model but with using my own data for precipitable water. I tried to change the grib2 files, which are used for calculations using program wgrib2 and examples from https://www.ftp.cpc.ncep.noaa.gov/wd51we/wgrib2/tricks.wgrib2, but it seems that original grib2 files are not changing. Is there another way to insert my own data to the grib2 file?
