When you add a new release by using the the Discogs Import Release GreaseMonkey Script (or by importing songs from Jaikoz which were already matched to a Discogs release the Discogs Url) the Discogs url is put into the Edit Note it would be nice if that was enough to make the Release Editor automatically create a Release to Discogs Url Relationship. As it currently stands now you have to go back into the newly created release and do another edit just to add this link
