Not sure if this will work for you given the directory structure you have those in.
But you could try copying a couple and see if it works for you.
I have all my one-off specials, live events and documentaries in my Specials folder.
So put in your TV Imports folder a folder names Specials.
TV_Imports/Specials
This feature was added in Sept last year
I currently have 146 videos in that folder and after importing they show up under TV Shows.
If it's unmatched on import
It appears like this in Library>TV Shows with just the filename for the Ttitle
