Why even after you organize the event would it keep separate events?
What I figured out is that if you have red file, which means it needs to be reconnected, if you re-import the file back into the event then it automatically reconnects the footage.
It will reconnect the footage even if it has changed places.
Obviously the media has to be the same footage from before with the same duration. You can recapture the footage and give it the same name.
