Option to rescan for g-metrix files?

During the upgrade via version 3.3.0 beta, I've lost the link from the raw video files to the .fit files. This is a bit annoying. I can re-link them when creating a video project, but not in the media library. Is it possible to have an option to rescan for g-metrix data? It looks like it'd be pretty easy to match up the video time to the .fit files in the g-metrix folder (I'm assuming the only place this is required is in the video.xml file).

The thumbnails also got removed but I've managed to copy them from the previous (pre-beta) database folder and they all look to work now. I did try to copy the video.xml files over as well but the format has changed so it didn't work.

Thanks,
Brett
