In Jira Automation how can I update all the sub-tasks of a parent when a field in the parent changes

Cash Coyne_tanpr0

When an issue that has sub-tasks is updated, I want to copy certain fields from the issue to all of it's sub-tasks with Jira Automation.

I see how I can go in the reverse direction where I can trigger on a sub-task change and copy from a parent, but not the other way around.

Any idea on how I can make this happen?

You do that by using the branch rule/related issues, that allows you to update all subtasks associated with the triggering issue.
