I'm using an automation that adds the parent name and then a colon to the front of story summaries when a parent issue is added:
{{issue.parent.Summary}}: {{issue.summary}}
But this means that if someone changes the parent, then we end up with a story summary that has two parents at the front
New parent: Old parent: story summary
How do I create a rule that overwrites the original parent?
[The current rule won't work if issue creation is the trigger, since you add parent info after issue creation.]
