How to configure the "display name" in from email address only for journey assigned email alert.

Summary:

Our requirement is that whenever a new employee joins the organization, a journey will be assigned to the newly hired employee, who will then receive an email notification with the from address "podname.fa.sender@workflow.mail.em2.cloud.oracle.com". The new employee might get confused by this unfamiliar email address. To make the email more understandable, we have specified an alias name in the "Email 'From' Display Name" under application preferences. However, this causes all notifications triggered for other modules to also receive the same display name.

Is there any way we can configure the alias name specifically for the journey emails only?
