I dont believe plex can do this from what i have been googling around for, but perhaps it can?
Basically i enjoy watching a full season at once, then wait for the next season to fully air before watching, dont like waiting weekly, and there are enough shows to switch up too so i can still watch something lol.
Ideally it would be nice if a icon or text note could be appended from IMDB or manually by myself, so i know if a show was canceled, completed and over, or expected next season air time
