I think I've got it. I created a new Style item in my source flowchart page called "Flowchart". It had all the correct settings so the chart appeared as I designed it.

I then simply copied & pasted over into the target document and it pasted correctly and I can select individual objects within the flowchart so I can add my hyperlinks as desired. Now when I save as a PDF file hopefully it all works as I hope.

Thank you for input, the Style naming I think is what allowed it to be copied, instead of the Default "Normal".
