I need playback of a video to be ganged with a selected audio-only clip, sometimes with an offset from the start (of either one). Use case: I'd like to be able to evaluate a set of music files to accompany real estate videos.

I thought I'd be able to do this by setting audio as a reference but that's not currently allowed. So I set the video as the reference but it just jittered back and forth over the first couple frames while the audio played back.
