Can I copy reports from one form to another

I'm afraid that reports cannot be actually duplicated between forms. We may however, open a feature request for this, although we cannot provide an ETA, we would keep you updated via this thread. 

Thanks. 

It just seems like when you duplicate a form it should duplicate the
reports as well. That's the easiest way to do it because all of the
different fields would be the same.
Thanks for responding.

Upon performing some tests I found that cloning a form also clones the PDF documents, you may give it a try and let us know if you have any questions. 

Thanks.
