I use a file with many worksheets that use the same custom header and footer.
The header and footer are updated frequently. Is there any way to make the
updated custom header/footer available in the the header/footer drop down box
in Page Setup. I would like to be able to update the header once and have it
flow to the other worksheets. Unfortunately I do not use headers/footers
other than in this file, so if there is an easier way to update the
header/footer please let me know.

Thanks
