'Replace pages' not modifying form element positions - is there another way?

Question

PDF form design in InDesign, bring pdf into Acrobat to add field validation JS. All good.
Modify form in InDesign, 'Replace pages' in Acrobat to get new design changes in without losing JS. 
Good, except Acrobat won't bring across any altered positions of form elements, only non-form elements like text and images.
Adding the JS to the PDF created by InDesign each time the form changes is time consuming.  Tried adding the JS in one go via "Edit All JavaScripts" but Acrobat won't retain. It seems to want each form field's JS added to it individually.
Is there another way? Thanks.

That is exactly the point of the Replace Pages command. It replaces the underlying page while maintaining the objects on top of it in their place.
If you want to insert a page with all of its objects in tact then you should delete the old page and then use the Insert From File command (under Tools - Pages) to add the new pages. I believe that will do what you're looking for.
The 'Insert From File' I expected would lose any script I've applied to an element previously on the page, which would be totally understandable. I guess the form elements are in a tricky position, being both an intrinsic part of the design (InDesign) and Interactivity (Acrobat).
