In my team, some team members occasionally get assigned to urgent tasks outside of the team, which aren't always known in advance and therefore they can't be planned for in a sprint. However we still want such issues to be shown on the Scrum board, ultimately as an Expedite swimlane or so. But, how do I achieve this? I have changed the filter query for the board to "project = MyTeamsProject OR (project = ExternalProject AND labels = "my-team")" but no new issues appear in the Scrum board. Help?
