I would like to be able to have additional User Story / Defect subscription criteria that allows me to be notified when a Story or Defect's child tasks / tests change status. For instance, maybe I'm listed as the "owner" of a story or defect. I would like to know when the tests on "my" story have been moved to "Passed" or "Failed". We can do this for ALL tests / tasks, but there's no way to limit it to a class of stories or defects.
