Installing Fonts to Bernina 635.

Hello,  I know the 635 comes with 5 default fonts. I would like to add more. I purchased a font library online that is in EXP format. When I bring it over to my machine I am able to see all of the characters upper case and lower case. However how I do generate a library from it as similar to the the 5 default font libraries. I would like to be able to type the letters and let the machine go at it instead of adding each one, one at a time. Am I doing something wrong. Thanks in advance for any help.
