Media Library connected via USB functionality

I have a 2TB external HD attached to my WD TV Live player. I was streaming from my Mac Pro Desktop upstairs through Plex Media Server but I was getting a lot of hanging etc so I decided to try this.

Is there a way to set up the media library so that it shows me unwatched shows only? Or identify which shows have new content added? This was the best functionality of the Plex Media Server that I was using but it just kept hanging and it disurbed the viewing experience.

How can you set up a ‘local’ media library (on a USB HD as mentioned) with that sort of functionality?

Hello ShredAstaire,  unfortunately this options is not available, but you can make the suggestion in the ideas section.
