I was able to get this to work while using a large clip of the entire show I was working on.
I obtained the clip using the “crash record” function while it was being recorded to tape.
Once I saved the clip I went to the “BROWSE” menu, found the clip, right click on it, select the “Scene Cut Detection” option. This should automatically re-direct you to the “SCENE” menu. Here you hit the “Load EDL” button and proceed to load the first part of your EDL. Repeat this step for the second part, but when it ask you if you would like to retain the previous scene information click “preserve” and it will merge both parts of your EDL. You can do this for the remaining parts of your EDL, when you are done I would recommend saving your new EDL.
I have yet to try this with a multi-layered video timeline, you may have to compress that first in FCP or AVID…
I hope this helps,
