Oh, oh no. Your organization scheme is fantastic, don’t change that. Keep each season their own separate folder. Plex scans recursively in folders, so it will look for “Season 01” and “Season 02” folders etc etc WITHIN each show folder. It then presents a single MASH entry on the Library you can click, which shows all season folders within that:
Poirot has a bunch of seasons, let’s click on that!
Oh nice. A bunch of season entries, each with their own poster image I can change if I felt like it.
This is my file storage view. I pointed my TV Show library in Plex at my TV Shows folder on my storage device.
