Hide Staff Name on Receipt

Requesting an option to limit Staff Last Names IN GENERAL (including receipts and anywhere else staff names are displayed) to just the First Name and Last Name first Initial OR the option to enter a NICKNAME and toggle which can be used on events, receipts and reservations.

I feel this is too much information to be shared and could be a potential privacy issue if the staff are minors. And, this information is seen on auto-emails that currently cannot be customized.
