GX for plotting additional geological symbols in montage?

Hello - just curious if any GX experts are familiar with symbol tables that can extend the very limited geology symbols currently offered in montage? I see thrust faults, but no normal or reverse faults, for example. Just wondering if this would make for a good (entry level) GX, or if there might be a better way to approach solving this issue?

Thanks for any suggestions,
