Can the Name Normalizer transform be edited?

Does anybody know if the Name Normalizer transform can automatically remove accent marks (i.e. Colón = Colon)?

Also, I tested this transform and it seemed to work for many of my uses cases but one of my user’s last name had changed when it shouldn’t have been (i.e. Macasek = MacAsek) I understand the transform saw the ‘Mac’ and performed it’s predetermined action but is there a way to edit either the transform itself or write in an exception for an individual?
