I know I'm a good two years behind on this post, but did you ever receive any answer for this? I'm having the exact same problem and need a way to make changes at the top of the first page and it automatically update the same phrase on other pages. Similar to if you want the same info in different cells on Excel. You update cell A1 and all other cells with the equation "=A1" update to the same info.

Please let me know!

Thanks
