a new copy pattern variable would represent the directory structure relative to the folder that was added to a collection. especially useful for retaining directory structure when syncing to a portable player

ex:
/home/user/Music/ is a folder added to a collection
and
/home/user/Music/From_My_One_Friend/Bob_Dylan/blowing_in_the_wind.mp3

would want to sync to a portable as such:
**PORTABLE_ROOT**/MUSIC/From_My_One_Friend/Bob_Dylan/blowing_in_the_wind.mp3

could not find this feature anywhere, though it did take me a month to realize I could sync to a portable, and that was only after looking at the sourcecode while thinking about hacking my own sync solution.
