Create playlist with the same hierarchy as the folder we are importing

It would be a very nice feature when dropping a folder in the playlist it was making a playlist per "leaf" folder and following the hierarchy of the folder for the sub folders. For now, when dropping a folder in the playlist, it creates one playlist with all the songs from all the subfolders of the folder. Engine DJ from Denon has this feature and I would love to see it in rekordbox. 

Thanks in advance !
