Putting comma's in default number format for Excel 2013

[dhcpa]

I am a CPA so I used numbers a lot. I was able in the default setting to have the numbers show with two decimal places. But I cannot figure out how to in a default setting to have the comma's in each number. Currently my default number will show as 10000.00. I want the default to show as 10,000.00. The comma makes the numbers much easier to read.

I don't think that you can (easily) change the default but you can format the cells as Custom
