Affected username parsing in email templates

Hi All,

I have a question to see if this is possible. In email templates, you use a drop down to choose what you want to include such as processID, AffectedUser, etc. What I want to do is parse the "affecteduser" option to use their first name only. So, it would go like this:

Hello John,

Your ticket (processID) has been closed.

BLAH BLAH

Support team

Instead it goes like:

Hello John.Doe@contoso.com,

Is this possible?
