As kanban rapidboard users, we want the configuration option to have swimlanes by Epic SO THAT we can easily indulge in that very useful view if we want to.

Notes:

• Swimlanes by Epic are already in Scrum mode, but deliberately supressed on the kanban board. I understand the blah blah reasons, but not accepting of those reasons. Even just for consistency / minimising confusion it should be there.
• Plenty of teams may have a primary Scrum board (and even then because it's the only view which provides a Plan/triage view). And those teams may also use Kanban boards for other purposes - but confusingly aren't able to use the useful Epic data that it available.
• Sure, workaround is available by manually configuring swimlanes by specific Epic, but that's really arduous to setup, maintain and sequence.
