I’m in your same boat sort of.
I need the original source file names (adobe calls them component clips) for export to Pro Tools for audio mix.
I have one work around – which is to right click on each clip and open properties. Select the name you want as it shows the original path – then right click the clip again and select rename and paste the original name into it. It’s tedious as hell…worse than rotomonkey work, but I can’t afford an AE 🙂
Hope it might help or inspire a fix for you.
Cheers and Godspeed.
