On 8/27, I asked about getting a button for a custom number format into the
Quick Access toolbar in Excel 2007. Thank you to Bob and Roger for your
replies.

By right-clicking on Home Styles Cell Styles Number Format Comma and
choosing Modify, one can modify the way the Home Number Comma Style
button works. I am wondering if, once I modify the Comma Style button, I can
have the button work with the new format EVERY time I am in Excel?

Thank you, Brad E.
