Use 'Genre' in folder hierarchy / file naming paths

When extracting my music from a CD using Sound Juicer I prefer to have my music sorted by genres in my music directory. Example: Music/Jazz/Miles Davis/Kind of Blue/01 So what.

With gconf-editor I can access more advanced naming schemes but there is no field available for genre. I can only find these:

%at -- album title %aT -- album title (lowercase) %aa -- album artist %aA -- album artist (lowercase) %as -- album artist (sortable) %aS -- album artist (sortable lowercase) %ay -- album year %tt -- track title %tT -- track title (lowercase) %ta -- track artist %tA -- track artist (lowercase) %ts -- track artist (sortable) %tS -- track artist (sortable lowercase)

and these:
%at -- album title %aT -- album title (lowercase) %aa -- album artist %aA -- album artist (lowercase) %as -- album artist (sortable) %aS -- album artist (sortable lowercase) %tn -- track number (i.e 8) %tN -- track number, zero padded (i.e 08) %tt -- track title %tT -- track title (lowercase) %ta -- track artist %tA -- track artist (lowercase) %ts -- track artist (sortable) %tS -- track artist (sortable lowercase) %dn -- disc and track number (i.e Disk 2 - 6, or 6) %dN -- disc number, zero padded (i.e d02t06, or 06)

Is it in any way possible to add a genre to the path pattern?

To be exact:
/Music/[Genre]/%aa/%at/%tN %tt
