Importing Flexible Beatgrid Tracks from Serato

In serato i’ve had songs that have flexible beatgrids. Now i understand that 1.6 Engine Prime works with importing songs from Serato and including the flexible beatgrids… Is this correct? And would i need to re-import those tracks to get the flexible beatgrid data?

Thanks in advance, Mark

If the track is already part of your engine prime collection. You may need to.
