In a multipage form whereby three choices on page 1 redirect to page 2, 3, or 4 as appropriate, the Back button can't be controlled as to "back to where" - in every case, my answer would be "page 1" if I was on page 2, 3, or 4. But as it works now it just goes to current page -1.

So the idea or hope is to have the ability to include something like "Page 2 Back" or "Page 2 Next" actions to enable logic tree-style forms.
