My goal is this: I have a library, say it's called Series. I store my series in two different places, one for watched episodes and one for unwatched episodes.

Obviously I can simply add the root folder of each location to a series library. What I would prefer to do is have a sub-library within Series for each series, for example:

Series \ Lost

Lost (Unwatched series)
Episode 3
Episode 4

Lost (Watched series)
Episode 1
Episode 2

Is there a way to achieve this, or something approximating this (without having a full library for each series)?

P.S. I've read the other topic, but I was wondering if there was a possible workaround for this specific need. More out of hope than anything else. ;)
