As a scrum product Owner I habe the need, that Epics are affected by filters as User Stories are so that I only see big User Stories (called Epics), that belong to the filtered backlog.

Acceptance criteria:

• After I have choosen a quick filter on the agile planning board, in the left column of the planning board only the epics display, that match to the current filter
• If I deselect a quick filter or no filter is selected, all (open) epics of the backlog will be displayed
