Hi Mike

Thanks for posting in the community! To move individual parts of your process diagram onto separate pages you can copy the area you wish to move by selecting the shapes in that area.

Once those shapes are copied you can create a new page using the '+' button at the bottom of the page:

When this button is clicked a new page is created. You can then toggle between 'Page 1' and 'Page 2' and paste the copied material on to this new page. This should allow you to move individual parts of your process diagram to another page. Let me know if you have any questions!
