Communications inside of Event Management/Event Registration (confirmation, reminder, follow-up) allow the use of [first_name] but not [preferred_name] which seems like a big oversight.

Furthermore, throughout the rest of Enrollment Management, there is an invisible logic applied across all communications, where the [preferred_name] field grabs from the [first_name] field when empty.

Please make this update for consistency across the whole platform, as it's current use is limited and impersonal.

Thank you for considering it!
