title: How to control a built-in ribbon in Excel 2010
body: <p>For example, one of the things I want to customize is "Font>Borders>Line Style" being dotted line by default instead of solid line. How can I do this?</p>
  
  <p>I want these customizations set at the start-up of each excel session or permanently, which will help speed up my work. I am thinking to change the default programmatically via vba. But not sure if there is any object model allows me to access the built-in ribbon. </p>
