I have an issue type that must be approved by a set of reviewers, before transitioning to the next status. Because the amount of reviewers varies for each individual issue, I have a lead reviewer designated as the assignee when in review status. All additional reviewers are identified in a single custom field, and are assigned as watchers. I need a way to have the lead reviewer know when the additional reviewers have reviewed and approved/denied the progression of the issue.
My thought is to have automation create a sub-task for each user that is added to the custom "additional reviewer" field. This can vary between 0 - 5 reviewers for each issue.
Unless there is a better solution, how would I write an automation rule that creates sub-tasks for a field that can have any number of users?
