While the "Show only results that are in my subscribed entities" option for reports works nicely for subscribed artists, it doesn't seem to do anything for subscribed labels: http://musicbrainz.org/report/MultipleASINs for me should find http://musicbrainz.org/release/80603f4a-0db0-4945-beca-5d7181b5b46b (I'm subscribed to Chandos) but it does not.
