I think I understand what you mean. It’s pretty well explained above.
So how about adding markers as a Media-Bay asset type and then be able to open/locate to it?
In other words markers like audio files would be scanned by MB and end up in the database. When doing a search in MB the markers would show up (if selected) and then the option would be given to open that project and locate to the marker straight from MB. Perhaps this would cause databases to balloon to tremendous sizes if all markers were included, so perhaps a new type of marker could be created or filtering the inclusion to the database by prefix or suffix.
Would that be closer to what you’re looking for? It’s really the only addition that comes to mind that seems to address what you’re looking for.
