adding a duplicate page to fill out without changing field names

Hi, Okay...I'm filling out a pdf form that wasn't created by me. In DC Pro.  On a Mac.

I need more pages to fill in information. If I duplicate the page, whatever content I enter is entered on ALL of the duplicated pages. 

I can't change the field names, because it's a government form. But, I need extra pages to fill out all of the info required. 

How do I make dupliate pages that I can fill out with different data without changing the field names?

I'm stymied and can't seem to find a solution. Thanks for you help!
