Using Jira Portfolio, I have created a project called Initiatives (with the Initiative issue type). I have an existing legacy project called Development. I have the epics created under development and now i am tagging them under numerous initiatives in the initiative project i have created. Now, in the gantt chart, I want to see by initiative, a view of the initiative, the epic and the stories for one particular initiative only. Is that possible with the way I have set it up?
