Phone number format on Web UI

We have a similar use case what is posted blow where we need format the phone number to (xxx)xxx-xxxx on the web UI before a new user can be added. https://www.quest.com/community/products/one-identity/f/identity-manager/5949/phone-number-standardization-in-self-service

We cannot do this at the template level, because our customer has other types of users that are added into the system from DB and CSV and we don't want to format/validate those users. Is there a way to do this on the web UI?
