Labelling swim lanes in a boundary

[skiwi]

Like in a diagram, a boundary allows you to have swim lanes

But how do you label the swimlanes and set their background colour?

What you see is what you get... There are no options to fill individual swimlanes, label them or set their sizes.

You could use the Swimlanes Matrix facility, rather than a Boundary with Swimlanes.

Thanks, I am using swim lanes and matrix, but this would have been a better option.
Sounds like a feature request then.
