Unique Menu for specific pages

Hi

I am desperately in need of adding an additional menu navigation bar on to specific pages.

There are several conferences and for each conference there are a set of specific pages relevant to that conference only and so I would like to be able to add another menu on the conference page that allows the user to navigate around the relevant conference menus. I currently use Mega Max Menu, but it seems I can only create one additional menu in the theme and so it will only work for one conference not 19.

Having a look through forum history you have recommeneded WooDoJo but thats not available anymore. Please tell me there is a resolution to my issue or I am in trouble :-p
Thank you
Angela
