Derek,
You can add this info as meta-data tags. You will have to define your own
names for the keys. Something like pix_1_class, pix_2_class, etc.
To add these you can use the -mo option with gdal_translate[1] or use a vrt
file[2]. You can create such a vrt file using gdal_translate too by setting
the output format (-of) to VRT.
