In, for instance, in Mozilla Firefox (the browser), you can mark the whole text in the menu you already have ready in your browser when you are looking at your website, and right click, then select view source for selected text.. then copy this code. sure there must be ways to do this in other browsers as well.
Copy that code, and paste it into one of all of your pages "text box". You can do this through the power edit button, when you have chosen all pages of yours: (not sure what to choose for other templates, but the one I use for my sky page is text box 2), choose text box 2, choose to have a global change, then click proceed, then you can paste in the menu, and you're done.
Works for me, and is very easy when done through power edit.
Saved me a lot of work!
