Since you use Dreamweaver, just do the following. Open EVERY page that has the change, then use the piece just before or after the change and use find/replace all.
For example...
Code:
<a href="http://link1.html">link1</a>
So I tell dreamweaver to find the avoid and replace it with...
Code:
<a href="http://link1.html">link1</a>
<a href="http://link2.html">link2</a>
And make sure the option is marked to do it on all open pages.
If this doesn't work like I recall, you CAN do it for certain with a tabbed notepad editor like Editpad.
Jam it back in, in the dark.
