So I'm using the clips circled in red as audio-only. Originally they were below the primary storyline. Primary was/is a gap clip at this point.
To add some dissolves, I created a secondary out of the broll above it. When I did that, the clip that was below the primary moved above it. Made no change to playback. But now I'd like to put the clips circled in red into the secondary - again, just to keep things tidy.
Problem - I can't figure out how to get them into the secondary, and not move things around in the secondary timeline!
