As far as I can see, there is no way to locate the Phabricator equivalent of a Mingle card. (This is in part due to search sucking so much in Phab - e.g. it should be possible to find T77739 by searching for 861 or https://wikimedia.mingle.thoughtworks.com/projects/multimedia/cards/861 but neither actually works.)
Is there any way to comment the Phab number in Mingle, or set the Mingle number in the reference field in Phab?
