Adding new navigation bar at the BP Blogs MU Theme


in my previous question, using the Daily Theme, u suggested that I can remove the menu navigation bar if I want.

Now I'm building my second website, using your other theme - the BlogsMU. In this theme, there is only one navigation bar, and the new menu from the WP 3.0 not supported.

Is there any simple way to add an additional Navigation bar using the new WP 3.0 menu in the BlogsMU theme?

Would be great if you can advice me how to do it? Thanks a lot in advance.
