Alright, this is a little embarrassing.  In Excel I use the Formating tool a bunch for setting custom formats or adjusting precision.  I just learned today that there is a Formating tool in the Home tab of Excel, where as, I don't need to right click, select Format Cells, go to the Number Tab and then insert my formating.

There is a small button that would take me there right off the bat in the Home Tab, and a pull down menu to change the generic formatting and other buttons to adjust the precision.

Color me embarrassed for not noticing for a few years.
