Preparation list storting edit

Hello, i would really like to have the same sorting and list editing options for the preparation list as for other playlist. Also, i would love to fill the or a preparation list from multiple sources like an usb in player 1 and another usb in player two. But i can figure the last thing is pretty hard to manager technically. Furthermore, it would be pretty handy to import history lists back into engine prime. Now i export a history list to .nml then import into traktor and then import back to engine prime. There must be a better way. Same with library manege ent after filename alterations or moves. Let traktor fix it and import back to EP. I hope these van be passend on to the dev team. Much apriciated. Keep up the good.
