cutting and adjusting v/o tracks

So here’s a question;
In putting a video together, I sometimes want to cut a v/o track to better sync it with images/video clips. Is there a way to do this within PhotoMagico? Can’t seem to find a way to do this and a search for v/o in the forum produces nada. So I have to currently use iMovie, which easily allows for spitting an audio track.
Thanks
