Show guest stars for TV shows

On v3, I have no way to see episode or season guest stars. I would use this daily to help me figure out why someone looks so familiar, or find out what someone new to me has been in and maybe add more of their stuff to my watch list. Currently, only season regulars are shown at every level (show, season, and episode). I would like to see the guest stars row or toggle at the episode level at least. Thanks!
