If you took a confirmation name, do you use it as part of your official name?

I don’t know how many religions use a confirmation name – the only one I know of is Catholicism. For those of you who have a confirmation name, do you use it as part of your name on things like job applications, credit card applications, etc.?

I knew a girl in college who did, and I always thought it was odd. She used two middle initials. (Example: Ann M.E. Smith.) I have several Catholic friends and relatives, and none of them include their confirmation name in every day use.

I ask this only out of curiosity, nothing more.
