Rekordbox Mobile Sorting

Hi All,

Just getting to grips with Rekordbox after moving from CD's. I'm transferring playlists from Rekordbox on my Mac to Rekordbox mobile on my iPad. Am I correct in saying the best way to sort playlists so that the the newest imported tracks are at the top is by re numbering the order and exporting the whole playlist each time i've added new tracks? If so it seems stupid you can't sort by date added on the Mobile app like you can on the desktop version. Is this a feature which is likely to be added? 

P.S does it work the same way when exporting to USB as well?

thanks
