The problem is that #-#.# is not a supported numbering format. Format Page
Number only allows two distinct numbers and I need three (chapter, page, and
point page). That's the issue: How to use a page numbering format that Word
doesn't support without screwing up the ToC and Index.

As to changing the format, that's not an option. The engineering department
has been putting out this publication in this format on an annual basis since
the 1950s. They're not going to change it just because Word doesn't like it.
I'm more likely to convince the IT department to switch to Word Perfect than
I am to convince Engineering to change their page numbering scheme. Of
course, what will really happen is that we'll end up having to disable the
automatic ToC and Indexing features and enter all the page numbers by hand.
But it would be nice to find a way to avoid that, if we could.
