Whoa... wait a second. I can promise that CSS Menu Writer is not far behind others. There is an easy way to fix your problem with a little logical thought here.

Is what you want to do is find the code before and after where your menu will go on a page that currently does not have the menu. Let's for arbitrary purposes of example say it looks like this:

Some more stuff here.
Now, let's pretend you want that shiny new menu of yours to be the first thing inside your "innerContentWrapper" on all the pages. It's simple, one quick Find and Replace with Dreamweaver will do the trick.
You could find every instance of
And replace with
<div id="myMenuHolder"><?php include the menu ?></div>
