Editing Media Structure

Hey Guys!

Is it possible to edit the MediaMenu Structure in XBMC?

I want to edit my Startscreen to sth. like:

Movies (with two Subdirs "Archive" and "New"), Musicvideos (one folder), TV (again, two subfolders "TV" and "Documentary") and so on..

Basically adding the entry "Musicvideos" to the startscreen and editing the "Movies" option in order to directly select one of these folders seperately i do not want them merged in one single library (that they are written "under" that entry so that i can quickselect them)

Thanks for the help guys!
