I think the answer may be “yes” and “no”. I would suspect that the matters are contained in the records of the parish in which someone resides when they become a member of the Church; but I do not know if that information is sent broken out to the diocesan offices; that is, baptized having belonged to a group that the Church does not recognize as properly baptizing (e.g. LDS, Seventh Day Adventist), baptized having never been baptized, and those who were candidates (baptized, e.g. in the Methodists).
and I am not even sure that any official records are kept by the parish other than the fact that a person either made a profession of faith, or was baptized.
