How to modify the employee full name on SSHR notification

Hi,

We have an requirement to display only the first name and last name on the SSHR notifications.

We did the modification on "Persona Name formats" from (First name||Middle Name1||Middle Name2||Last Name) to  (First Name||Last Name)

and run the CP "Update Person Name".

By running the above CP it changes on form level and also in LOV level but on the notification level still its showing the full name.

With the above changes we can achieve this or is there any other way to achieve the same.

Thanks,
