You can design a page layout and then create a page style based on it.
For example, you can create a page style that displays a particular header, and another page style that displays a different header.
Open a new text document, choose View - Styles, and then click the Page Styles icon.
Click the Styles actions icon and select New Style from Selection from the submenu.
Type a name for the page in the Style name box, and then click OK.
Double-click the name in the list to apply the style to the current page.
Choose Insert - Header and Footer - Header, and choose the new page style from the list.
Type the text that you want in the header. Position the cursor into the main text area outside of the header.
Choose Insert - More Breaks - Manual Break.
In the Type area, select Page break and then select “Default Page Style” from the Style box.
Repeat steps 2-6 to create a second custom page style with a different header.
