Is there a way to promt Recipients to review all form items assigned to them prior to final signing?

I have checkboxes on my form at the bottom after the signature field and these items are not "required" but I am afraid that Recipients are just skipping over them, because I have the Navigation setting on and when the Recipient signs, the navigation moves them to the final "sign and submit" button.  I can't make the checkboxes "required" because that would make the Recipient have to check the box and I don't want that.  I just don't want the navigation to skip over it.  Any creative problem solving out there?  Thanks in advance.
