I have got several teams working in separat "jira-projects". It is possible that several teams are working on one project together, each having their own stories in their separat "jira-projects". Now let's say we work on "Project-A", we have created a "fixversion" called "Project-A" as workaround to build dashboards that show the process of the project within all teams. I would now like to build a "Burndown" chart that shows me all stories with "fixversion" "Project-A", in order to see the burndown chart of all tickets.
Is that possible ?
