Is there a way to add “watched” to File Explorer?

Hi. I have some TV shows I want to watch just one time, so I don’t want to load them into the Kodi database. So I just browse to them in the file explorer, but there is no “watched” value being saved there, so sometimes its a bit tricky for me to remember which episode I should watch next. Is there way to add the “watched” feature to file explorer, or is there some other add-on that I can use to watch these shows and have a watched? Thanks so much for your support! – jeff
