How do I add expanding content on form in acrobat adobe 9 pro extended?

I have a form in acrobat adobe 9 pro extended.  I have 2 questions:  1) Can you make the main content of the form be continual (being it may or may not go into multiple pages) and 2) If the form goes into multiple pages, can signature area only appear on final page?

The form designer is Adobe LiveCycle Designer.

Thanks for any help given.
