As kanban rapidboard users, we also want the option to have swimlanes by Epic

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.
