Syncing an audio only input...

I feel like this feature is probably here somewhere and I'm just not looking right, but I have a mulit-angle video that I am trying to add audio to from an external mic. I can import it no problem, but I need to be able to shuffle it forward and backward so that I can line it up with the video. I had assumed I could select it in the synchronization tool and manipulate it like I would two video files, but I can only select videos and datasets. Is there a way to sync an audio clip?
