Swimlanes by Rank (regardless of sub-task)

We would like the ability to have our swimlanes based on the rank of the story in the sprint. I thought that the "Swimlanes by Stories" would do this for us, however it behaves... strangely. It appears to be based on whether or not the Story has a subtask, which is not always the case for us.

In the spirit of KISS, we simply want the stories in the Work board to have their own swimlanes and for those swimlanes to be ordered by rank.
