The Page Alias should allow you to do this. You can also use the Scrapbook.
Create a page alias (using the Sitemap, drag-n-drop) where you want the 'realtime' copy of the whole page.
If you only want a copy of the Content block, once created, copy it to the Scrapbook and add where needed.

Thank you....but a page alias will send me to the "master" page. The navigation will open the wrong parent item...

Th scrapbook wil copy the content, but won't link them to each other...correct?

No. Pages aliases will work just as if they were real pages under a different place.
Also, when using Scrapbook, other than the admin's, you can create an Alias when copying to the Scrapbook and paste the alias where needed.

Alright! Thanks.... I'll test it...

I cannot drag-and-drop files in the Sitemap. Is this an add-on? Am I missing something?

You should probably ask this as a separate post, otherwise you're guilty of "thread hijacking".
