Individually moving audio channels

I recently shot an event with a feed from the board and other from shotgun for ambience. I usually move the ambience channel forward to minimize the latency issues between the two audio sources. I can't seem to find a way to reposition the shotgun mic channel to match the timing of the line feed.

Right-click on the clip and select open in Timeline. Make sure the audio is set to dual mono and use break apart components.

Thanks Tom

I guess the problem I am having is that this feature won't work on a multicam clip. I take it into Angle Editor and then Open in Timeline and the Break Apart Clip Items is not available. I guess I will have to figure a way to do this before bringing the clip into multicam edit.

Did you set up the channel configuration before you made the multicam. I get this when I open in Timeline

No, that is the where I steered wrong. Thanks Tom. Do you just save it as a new compound clip then and bring it back to sync up with other camera?
