We have numerous teams that are set up in OpsGenie, but have a use case for severe issues where we'd like to create a single alert and notify ALL those teams at once based on their on-call schedule. This is easy to do by referencing each team individually, but that leaves room for error and takes more time. I want to reference ONE team (more like a group of teams) when creating a manual alert that reaches all of them.
Example: When creating an alert, I put TheATeam as the responder...which then alerts Team1, Team2, Team3, Team4 on call members.
What is the simplest way to do this in OpsGenie?
