Multicamera Sync by Audio with Track Assignments (Camera Label)

When creating a multi camera sequence by audio currently, it creates a new video and audio track PER CLIP.   When creating a multicam sequence by timecode metadata, it allows for track assignments by camera label.  Using camera label metadata, the end result is one video and one audio track PER CAMERA.   It would be useful in speeding up workflows to have this camera label functionality work when syncing by audio as well.
