Folders in Audio/Media

CREATE FOLDERS IN AUDIO TRACKS: Is there a way to create folders within the Audio Track/Media section? For example, if I have a number tracks from various artists, I'd like to group the tracks into their relevant folders according to artist and then subfolders such as Name of Album for the given artist. Does this exist in Proclaim? At the moment when I browse the Audio file it opens the entire list. It would be so efficient to have folders.
