When you first install Mezzmo, you are given the option to map Picture, Music, Video etc libraries to specific folders on a hard-drive, but how do you then remap the library folders to another drive at a later date?

I've installed a new drive that I've moved all my media to and I can't figure how to get Mezzmo to point to it. Only way I managed was to uninstall and re-install, but then you lose all of the metadata etc

Am I missing something obvious ?
