I found a way that is a little faster. If you select the 4 tracks in the project pane and right-click you can select “Merge clips”- when you do that Premiere creates a new 4 channel clip. I created an “audio” folder with a folder called “orig” nested in it. After I merged the first 4 clips I moved them to the “orig” folder. I kept doing that until I had merged them all. That way I didn’t get confused as to which ones I had already worked on.
Hope that helps.
