If the entire track is comprised of one wav file, simply slide it in the proper direction. If it is made up of multiple wav files, you can select the first wav in the track with your mouse, then press "shift" (or is it "ctrl"?? try each, I forget) and while holding it down, click on each of the other wav files in the track in succession. This will "select" all of the wavs in the track and if you slide one, they all slide in unison.
Is this what you meant?
