CCL:G: specifying solvent using IPCM

Dear CCLers,
I can specify a non standard solvent in a PCM calculation using G03W using the option "read" in the SCRF keyword. I would have thought the the same procedure holds for IPCM. Can someone enlighten me as to whether it is possible to define a non standard solvent using the IPCM method and if so how.
