Our marketing firm is seeking recommendations for automated workflow approvals for defined Sprints in Jira. We are looking for a function that would send notifications to multiple "approvers" at the beginning of our sprints to review and approve multiple work items assigned to a specific sprint. A plug-in would be great since our knowledge of programming in Jira is limited. Once approved, our sprint can be activated manually. Suggestions and/or recommendations are welcome! Thanks in advance.
