Layout tabs are great for page layouts and the Viewports dialogue box makes it easy to create consistent viewport layouts with every new tab.

Open a blank layout tab and type VIEWPORTS at the command line.  In the New Viewports tab, select Four: Equal and change the viewport spacing to .25".  If you have any saved views you can make them current in any viewport by finding the view name in the Change View to: area.  Pick the OK button and press the Enter key to make the four viewports fit the margins of the tab.

This setup can be repeated with total accuracy in any new tab with the same printer/ margin setup.
