Sorry for private mail.
I was thinking along similar lines, too. That is, a way to sync the audio and video from all sources in batches during the pre-editing phase (in the Resources window) rather than on the timeline, as we do now. This idea has been on my mind ever since I read, on Mantis BT 448 (and comment 0003983), a request from a professional; he said that CinGG would be fully usable in a professional production environment if it had this feature. The idea of importing hundreds of “Dailies” into the timeline and then syncing them semi-manually was out of the question— it needed to be done automatically during the pre-editing phase.

I've written down a lot of notes on how to do it, but I don't know how to put them into practice (and I think some of the steps are too complicated).
All the major professional programs have this feature, for example, DaVinci Resolve: https://blog.frame.io/2017/05/15/sync-clips-in-davinci-resolve/
