Select all tabs first by clicking on the first one, then hold the shift down
and click on the last one, then change headers and footers

I have a workbook that contains many, many tabs. I am trying to format all of
my headers/footers and margins at once, rather than go to each individual
tab, go to my set-up and make revisions there. When making changes to my
worksheet I can group my tabs, make a change, save, then ungroup and
everything has changed - it does not work like that for my headers and
footers. Any ideas? I really appreciate it and Happy New Year to you!!
