behzad, you could run through all your current pages and move things like buttons and NavBars to a separate layer, basically, all the items with page links.
Locking these would allow you to Cut & Paste the items your want to update on a page-by-page basis.
If there are Links in the text then change these to explicit links fred.htm rather than fred.
If you mirror all the pages and remove the content then even this will not be needed.
Pasting back could result in adjustments to the page length.
I might consider using Push in such circumstances.
