dynamic pasting in powerpoint

[riverfish]

Greetings forum and thanks to anyone who attempts to tackle my question.

I'm working on a wireframe mockup of a website for the company I'm working for. This will then go to a designer for the finished product. There will probably be at least 50 slides, each one with the navigation bar across the top. I have the basics for the top and side navigation bars, but most likely the titles will change at some point. Instead of changing each bar in each slide when this happens, I was hoping there was a way to create one bar on a seperate slide and then paste special it onto all the other slides so that when the original bar is changed it autoupdates all the copies. Is this possible in powerpoint?
