We have a lot of projects from which we create sprint boards for work that is shared across the company. We don't define the projects in the query so that anyone can be assigned to the workstream.
As the sprint management permissions are set at a project level this means that the ability to start and stop sprints isn't possible except for people who have full admin rights - which isn't sensible.
How can we give permissions to people to manage sprints without defining projects in the board query?
