We run multiple feature "sub-projects" on a single board. Each sub-project could have multiple epics, and each epic has multiple nested issues. To group the epics together, I added an Initiative at the top of the hierarchy (Initiative > Epic > Story/Task > sub-task). The issue now is that in my Backlog, there is a filter for Epics but that is no longer the highest tier type. Is there a way to create a filter that lists all Initiatives in a dropdown, and when selecting one, it lists all the issues linked to it (and its epics)?
It is also interesting that Initiatives seem to be created the same as issues, and are listed in the Backlog, while Epics aren't, considering that Initiatives are now ranked the highest. Is that an oversight or a bug?
