Tags, Folders, or Naming for Collections

[MaLaCoiD]

I have a collection of a radio show. In the filesystem, I organize it by year:
/Music/Radio Show 2010/
/Music/Radio Show 2011/
/Music/Radio Show 2012/
... each of these folders has a set of 4 files for each day:
Radio Show 2011-01-01- Hour 1.mp3
Radio Show 2011-01-01- Hour 2.mp3
Radio Show 2011-01-01- Hour 3.mp3
Radio Show 2011-01-01- Hour 4.mp3
Radio Show 2011-01-02- Hour 1.mp3
Radio Show 2011-01-02- Hour 2.mp3
Radio Show 2011-01-02- Hour 3.mp3
Radio Show 2011-01-02- Hour 4.mp3
The ID3 tags have varying Artist, depending on who hosted the show that day, and the Album is the date. The track number repeats 1-4 for each day.

The problem is that Subsonic is only picking up the first show, I guess since the track number starts over. Is there any way to have Subsonic list all files in the yearly folder, or break out each day into a unique album by Album tag, ignoring the filesystem folder?
