Replacing streamed tracks with downloaded versions and retaining ratings, tags etc

Hi All

Apologies if this has been covered but I cannot find anything on it...

I'm trying to exports tracks and playlists to a USB Stick to use on CDJ2000 NXS2's - I have a couple of playlists that have been made up using the Beatport Streaming service and I wondered if there anyway of importing the downloaded tracks and merging or duplicating the metadata and playlists i.e. my ratings and My Tags that I've already spend a good while on! I've tried to use Relocate Missing Files but it doesn't work, also tried just importing the tracks again and putting in the playlists but the ratings etc are only applied to the streamed tracks

Any advice would be much appreciated...
