Jump Menu

I got a website here
which I have used a lot of jump menu.

Now the problem is… I would like to add some pages more inside the website and I have to edit every jump menu in every pages in the website.

Is there any better way to edit the Jump Menu so that I can have the changes in just one touch… something like remote Jump Menu…

Can anybody here teach me or show me the tutorial for this kind of thing in flash? And is it easier if I build all of them in flash?
