Combining Category & Pages menu

Hello :

First, I want to say this has got to be the best theme out there. Customization is a joy, not to mention often a breeze. I do have one question, and forgive me if this was posted elsewhere (I looked...but that doesn't mean I didn't miss it). Is there a way to combine the two menus into one? I would like to have a category choice on the menu, which drops down and shows the categories...and then continue to have my pages, home, and other links.

Just wondering....thanks.

Masselyn.
