Could you please disable student's ability to change their first name?

Every month students choose names that are different than their first name on the roster. Last month alone, I have 4 students changing their first names. For example, Charlie instead of Carlos, JWho(?) instead of Justin, etc.

This makes grading more difficult since I consistently have to go back and check if they are the correct student. This is especially frustrating for student's whose last name is common, like Smith, Ortez, etc.

I understand FSO wants to be "hip" and allow students to use the first name they feel comfortable with, but can you imagine if the goverment allowed this? What name would you make up for your driver's license? I know I would choose "Jwho"...

Anyways, thanks for your consideration.
