Camera Type and Custom User field in file name

I have a couple of QHY cameras and would like to capture the name of the camera in the file name (168c or 247c). SGP captures the driver, but both use the same driver.
AND
It would be handy to have a user defined field (or two) where I could note any filter added to either of the above cameras or a manually set field rotation for a set of frames.
Thanks,
