Can we change automatic notifications so they don't show the advocates last name

[BSANSC2019]

When a notification goes out from Jira Service Desk, the email when include the full name of the person working the ticket.

How do we make that first name only?  

In today's world, I don't want my advocates sharing their last name.

I don't think this can be customized in JSD's core templates:

However using a third party app like Notification Assistant for Jira (web/marketplace)that we make allows you to build custom templates to support this kind of use case.
