How do I make commas with my sprite font?

So, I'm using a Sprite Font to keep track of my score since I want to use my own personal text choice. The sprite font is being used to keep track of the player's score but when the player's score gets into the 1,000s, 100,000, and beyond I want it to make the comma where it belongs. How do I do this?
