Keeping Subform On Specific Page

I have a 4 page form containg multiple subforms.

The form contains buttons for increasing/decreasing the instances of certain subforms - when these are clicked, this will of course will affect the location on the form of the subforms-move them further down. 

I have a whole page subform in the middle of the form and that I want to stay in the same place -  always be page 2

- even if someone increases the number of subforms prior to it in the hierarchy.  If a button is clicked which increases the # of instances of a subform, prior to the whole page subform in the hierarchy, I want the whole page subform to stay in place, and the form adjust around it.

Is there a way to do this?  Can clarify the above if needed.  Thank you for suggestions.
