Hi there, yes it is in the blog:

Though do remember that when you you see the itunes playlists in traktor its read only so you can’t do edits there. Also traktor will not show the value for key in the key column – copy the playlist to traktor collection/playlist and they do appear. So get you key writing software to write to comments field too. I also group by camelot key notation to the favourites above the the browser in traktor.
