Reply to Viewing tracks in Rekordbox??

Hi everybody.
New member of DJTT, so this is my first post. Hope you guys can help me

I have currently organized all of my music in iTunes, so that i can import the playlists to be used with any kind of DJ software.

I have a minor problem with Rekordbox though.
Let's take an example.
I have a folder named "Promotion". I then have a number of playlists in that folder, named "DJ XX" and "DJ YY" and so on.
When i select/mark each playlist i can of course see the tracks in that particular playlist, but i want to be able to see the content of all of the playlists, when i select/mark the "Promotion" folder.

It works exactly like that in Serato, so why not in Rekordbox? -Is it some sort of setting i have overlooked??
