For a 'Next-Gen' board, is it possible to have an epic which has stories in it that span across a number of other projects? If so, how do I set that up.
The reason I want to do this is that I'd like to use Jira's new roadmap feature to plan the work which will be done by different development teams using different Jira projects for their work. After doing some research, it seemed like I could create a single project with the roadmap that would contain only epics and have the stories within those epics assigned to different projects based on the team responsible for that story. However after setting up a couple of test projects, it seems as though Next Gen epics can only contain stories within the same project.
