Two Page Menus

Does anyone have a plug-in or hack to be able to have two different page menus? For example, say I have 10 pages. I want to be able to assign 5 pages to menu A and display it in the sidebar. I then want to be able to assign the other 5 pages to menu B and display it in the footer area.

I’ve done some searching and can’t seem to find anything.

Thanks!
