Exporting Rekordbox 6 tags to a CDJ3000 via USB

Hi, I know on the CDJ3000 you can tag tracks but once you turn off the CDJ or remove the USB the tag list is lost (I think)?

So I thought in Rekordbox I'd tag some of the tracks in a playlist and want to export all the tracks in my playlist to a USB, it doesn't appear to export when I use the sync manager

I then want to put the USB into my CDJ, once I'm in the applicable playlist I want to press tag list and it show the ones I tagged in RB.

The reason for this is I want the tag list feature to show my favourites in the playlist.

Or am I going about this all wrong?
