We will support several agile projects in our organization in the following months. We would need a general setting for non-working days or maybe a default setting (like a template copied at project creation) that individual teams could edit according to their own work schedule.

Also we would need a way to batch-add new holidays as we might have some long running projects spanning over years.

In the meantime, is there some groovy script or any other workaround to add a holiday to all projects using Jira Agile?
