change table of contents

[Michael Frisbie]

I am required to follow a format that specifies that the appendix pages
should be numbered as A1, A2, B1, etc.  Using the fancy header package I
have been able to display these weird page numbers on each page, but I
need to change them in the table of contents.  Is there a way to force
an entry in the table of contents to have a certain page number?

Thanks,
Mike
