Recovered audio file but lost edits: Overlay edits on new track?

Hi folks,

I'm certain I know the unfortunate answer to this, but I worked intently for five hours today and just lost it all so I'm grasping at every conceivable straw. Here's the situation:

I have a podcast recording that I was editing heavily, removing pauses and ums, scrubbing back and forth over every singular second of the track. I spent nearly five hours on about 40 minutes of content when Garageband crashed. I wasn't too worried; I was saving often. When I reopened Garageband, it asked me if I wanted to open my save or restore my project from an autosave. Since I'd last saved maybe 10-15 minutes prior, I opted for the autosave, what could it hurt? (Famous last words.)

Well, it looks like the autosave was corrupted and in opening it, it overrode my previous uncorrupted save. Suddenly, half of my recording (purely the stuff I had worked on so far) was reported missing, with the waveform absent on the edited track. Playing over this half of the track has no sound. Opening the project again showed no change which is where my autosave-overriding-original-save theory came from.

Now, I've researched this already a bit and I was able to restore the actual recording aiff file by Showing Package Contents, so I'm not worried about that, but I already had a back up of the file itself so that was never a concern -- I want my edits back! They're still there! Just empty, without the track data.

Is there any possible way to insert the unedited recording on a separate track, then apply the same exact edits to it retroactively? Like how you can lock the volume automation and copy it between tracks. The edited (although silent) tracks should still have some sort of timestamp data, right? In theory, couldn't you apply those identical cuts to any future track?

I say "in theory" because I realize there is no reason they would have programmed this feature. In what common situation would you ever need to do this? And it's not like Garageband is as feature extensive as, say, Adobe Audition.

So I already know the answer: "No dice." But I have to ask anyway. If only just to hear no from someone who would know better.

Thanks guys. I appreciate any thoughts or suggestions.
