I manage multiple projects and am assigned the 'jrs-owner' role. With this role, I am currently able to create sprints on all boards. Each project has one primary board whose name starts with 'JA - ' . I want to restrict sprint creation so that sprints can only be created on these 'JA - ' boards. Users should be restricted from creating sprints on any other boards within the same projects . Could you please provide validation rules, workflow configurations, or any other solutions to achieve this requirement?
