Can the quote creator be changed from Superuser to the current Username?

Summary:

When creating new quotes, the quote creator is by default the Superuser, even the _system_user_name (Current User's Name) is returning the Superuser instead of the actual username.

Content (required):

Every time a quote is created, the creator field is holding the Superuser name, tried to mark as default the value of _system_user_name (Current User's Name) but it is still returning the Superuser which is not correct.
