I don't think this feature currently exists, but would be extremely helpful with the form I was working on.
Due to the length of a multi-page form I was working on, I needed a way to quickly get to a specific page instead of having to fill out all of the required fields for any earlier pages. For example, I had a CSS styling bug with the date picker which was on page 5 of 7. Having to fill out 4 pages of form data is tedious and time consuming, especially when the bug is hard to diagnose and requires multiple attempts to fix (this one fortunately did not).
In the future, unless this suggestion is implemented, I'll just not use paging until the form is otherwise perfect, but since I work interactively with clients on these forms it is best to show them the form with paging (some clients can't visualize what the difference is, they need to be shown), thus it still creates something of an issue.
My recommendation is to add a 'disable' option to the multi-page properties so that people who are debugging aspects unrelated to paging can do so quickly.
