Commenting in Traktor in Itunes

Hey guys,

as I am practicing I want to edit the comment section of my tracks.
They already have the key from MIK in it.
But I have all my playlist in Itunes because I usually sort the songs in Itunes - so how can I edit the comment section without importing the complete playlist to traktor? I don't want to re-add the whole list everytime I add a new song (e.g. to a playlist for a certain show) or re-add each song seperately

I tryed to enable the Itunes tags to be edited from other programs - well, that's the first idea i thought of.
syncing itunes and traktor the whole time would be really anoying.

thanks for help,
Attix
