sync multiple wavs from another software ?

Hi! We recorder multiple different songs in another PC at cubase software. Now the only way to import thse wavs is by DURATION. Since that is the only thing that tell´s me they are all from the same song.

My problem is that when I drag those 10 wavs to my multitrack session, the order on them is different on each song! The bass drum goes on 1st track and it might go on to 4th on next song.

This is cos even if I use the sort by "duration" column on project tab in audition, the wavs are in random order - the bass drum wav is not the topmost on the list. Please does anybody here have a deeper understanding of mixing music projects recorded at another software, like cubase?
