I would like to use automation to create tickets across multiple projects. The problem I am running into is that I want to use a manual trigger, but I don't want it to be triggered from an existing issue. The trigger is dependent on an outside event that cannot be forecasted or schedule. I was hoping to just click a button and have the tickets across multiple projects created. I know it is easy to manually trigger ticket creation within a single project, but I am looking for the same functionality across multiple projects without manually triggering the event from an issue.
Is this possible?
You could try to create a Scheduled rule. Add any schedule that you want and keep the rule disabled when you don't need it. Once published a "Run" button will be displayed on the top right corner on the rule page. You can use that button to trigger the automation rule instead of waiting for the scheduled time.
