if you are talking about chtype 15 and 16. My answer stands....
If you are talking about kodi SmartPlaylists anything is possible. So yes then you can filter one season from on show.

Sorry, I was a little vague. I'm talking about smart playlists. I'll have to tinker around and see what I can do. Thanks mate.

You can try making your playlist exclude shows with a watch status of zero, or include only greater than 0. This should include only shows you have watched, thus ignoring shows you have not.

I completely I forgot you can set that in the playlist options. Thanks for the reminder
