How to put page numbers in side margin of landscape orientation?

[audit annie]

We need the page number to appear in the left side margin of a worksheet that
is part of our annual audit, but bound (book form) in landscape orientation.

Margins for headers are not the same as the margins for the body of
the printout, so as long as these are outside the main body you can
set up a custom header in the left panel and press the Enter key
several times (to get several blank lines) before inserting the page
number.

Hope this helps.
