Use playlist from USB device at another laptop

Hello Pioneer and Rekordbox DJ users.

I have two laptops with Recordbox. One of them i use at home, and another  at the club. At home i prepare my playlist's, i put cue points, loops and other.

The question is: Why i can use prepared playlists at CDJ's players as ex. cdj-900 nexus, but can't use them at another laptop with rekordbox dj at perfomanse mode and ddj controller?

p.s. library at the external drive is not the solution for me. i only wont to use the playlist's what i export to the usb drive.
