Import Samples to Rekordbox

Hi,

is there an easy way to import the sample library that was given after completing the survey to rekordbox retaining its structure.....

If I select import folder, everything is added to my collection (no subfolders or anything) creating a mess with my tracks.

The Sampler Plus pack is in a different format (.app)  than the one provided after completing the survey (.zip) and this installed wonderfully

I have tried added the samples to the samples folder but rekordbox does not pick them up.
