I need to set the margins differently for the first page than the rest of the pages.

I've messed around with inserting section breaks (as from what I've read is that Word creates a section break when you choose to apply "this point forward" from the Page Setup Margins tab, but I can't seem to consistently create a continuous section break at the start of the second page.

If not section breaks, any other way would be fine. Need to adjust margins to match new letterhead design for a bunch of existing documents so am planning on fixing the margins in a sub-routine when the print button is clicked (part of another macro).
