Currently file organisation patterns move files within the same library. For example, if you had two libraries:

C:\Music\ripped
C:\Music\live

And a pattern:

<album artist>/<album name>/<tracknumber>-<track name>

That would move files within each respective library.

But what if you wanted to move files between the libraries? Here's a way it could be done:

<library:C:\Music\live><album artist>/<album name>/<tracknumber>-<track name>

All files would be moved into the C:\Music\live folder, then into the correct artist/album structure.

Combined with having different rulesets for different libraries, this would afford a way of having a "quarantine" or "staging" library, then moving files into your "live" library once fixed.
