Sorry but there is no way... Once you synched clips, sound became like is audio from camera and there is no possibility to bring audio metadata to pro tools or relink the original audio files in some way in pro tools. I keep asking Black magic to address this problem but no answer in years. Hope this tread could rise the problem once again.
Once I tried a complex solution with an audio editor who did the job, but it wasvery tricky, using conformalizer, you export an edl with all the audio files on a timeline and an edl of your edited timeline, and you compare the two in order to recreate a protools session with the original audio files.
