I would recommend having a server option to toggle auto or manual modes for a rewatch feature, the manual mode will allow the user to click a ‘mark for rewatch’ option on a tv show and auto mode would allow plex continue watching algorithm to work everything out for the user so when all episodes of a show have been watched they still display in the continue watching list by using the watch history to work out which episode is the next one, a better description of the auto mode can be found here [Feature Request] Improvements for the continue watching algorithm
