Is it possible to add a new Event to be used for User Category: Notification

Summary:

We are trying to add a new template notification under Security>User Category>Notification to cater the requirement of our client to add an additional recipient for every password generated.

However, we can't seem to find where the Events field dropdown is being managed or updated so we can add the event. We are thinking that this is possibly seeded and predefined, hence cannot be edited or updated.

But we would like to get the concurrence from the SMEs here before we communicate back to client. Or advise if this is possible to do in Oracle.
