[Avid-L2] Syncing audio, an automated method?

Just got in some tapes from a shoot, HDcamSR 23.976 frame rate. 20 1 hour tapes.

Sound recordist put audible 29.98 tc on channel two of the HDcamSR and fed that same timecode to the slate, and recorded BWAV files. He didn't bother to send any of his audio (other than the TC) to the HDcamSR deck. There are hundreds of start/stops on these tapes.

Is there any way to automate the audio sync process? If I could digitize both timecodes into the AVID with the video, I could import the audio files and use autosync.

If I could generate a flex file or ALE for the video to show the relationship between the 23.98 and the 29.97 timecode, I could get to autosync that way.

At pesent, my best idea is to import the BWAV files, then layback each piece to the HDcamSR masters based on the visible timecode in the slate window. Tedious at best.

I realize I could also do this in the AVID, once I have digitized everything, but these tapes are for a promo shoot that is going to be used by several different vendors, and I would like to solve this once, so all future users don't have to hassle with syncing the audio every time they use this footage.

Any ideas out there?
