Send to all Email fields on the form

The forms I am implementing are for general HR requirements, when an employee is completing a form they must enter their own email address (a copy for their own records), a Line manager email address (they need to be notified when requests are made), a HR Manager (some of the emplopyees requests require a supervisor to be aware of the request). When the employee submits the form notifications need to be sent to all of these entered email addresses.

In summary Is it possible to send notifications to all email fields used on the forms rather than only being able to select one? aswell as using routing to determine which department the form should be sent to.

Ok I have checked out your link, in order to maintain the usability of the solution i am implementing, I would like to write a generic PHP script that takes the field values and parses them into a table (similiar to the out put that gravity forms already does) but grabs any email fields and sends this output to all of them.

In summary a generic script that parses the values for email addresses and forwards to all of them. I am unfamiliar with Gravity Forms, is there a simpler way to achieve this? perhaps using the Gravity Forms Plugin? It is imperative to maintain the usability
