TV Shows Watched and Unwatched

When in the TVshow nodes, you can toggle between Watched, Unwatched, and All Videos.

This has an effect I need to replicate through smart playlists or custom video nodes, but cant figure out how to.

Say I have a Watched TV Show (all episodes watched, a Mixed tv show (6 episodes watched and 7 unwatched) and an Unwatched TV show all episodes unwatched).

I want to create two playlists or video nodes.

The first replicates what happens when you toggle to Unwatched Only:
It shows two series:
* The Unwatched Show
* The Mixed TV show (and when I view that show, it shows only the 7 episodes left to watch)

The second playlist replicates what happens when you toggle to Watched only
It shows two series
The Watched Show (all episodes)
The Mixed TV Show (Only the 6 episodes that have been watched are visible)

Any suggestions?
