keynote 09: can you control length of dashes in a dashed line?

Previous versions let you control the length of the dashes in a dashed line. Now, not so much. Or have I missed some secret way to alter the length of the dashes?

This retrogression in functionality is super annoying. Why would anyone think that (a) all dashed lines would look best at the same length of dashes, and (b) keeping the ability to control the length of dashes would be too confusing?
