Conforming DNx Proxy to BMPCC OG (HD) DNG Original Problem

Hello all, I have a edited timeline in Resolve Studio 19 that uses DNxHR proxies (that I transcoded externally back when I used Premiere) and now I need to conform them to camera originals for grading.

The problem: camera originals areold Blackmagic Pocket Cinema Camera HD DNG Raw sequences;

I tried different methods such as reconforming from bins and from media storage; they work if I check "Loose Name Match" (which is expected, as I am conforming DNxHR .mov files to CinemaDNG image sequences) but, it doesn't mantain the editing; the clips are correctly replaced, but the editing is off; I guess the reason is timecode, so I tried to check "Timecode" too, but I get this error:

It's 5hrs worth of footage so I really need to find a way to batch conform or replace the proxies correctly; do you know some workaround?

I think the core problem is the fact that my proxies are audio+video files and the camera original are CinemaDNG sequences bundled with a separate audio track (which Resolve sees correctly as a clip, but the problem stays)

Can you suggest a method or a workaround?

Thanks everybody for your help
