Additional Request Fields _ can they be made mandatory?

I have my ServiceDesk Plus system set up so that only supervisors can submit requests via the web interface. In order to make this work, I have set up Additional Request Details fields for name of user needing assistance, office, phone, and system ID. Unfortunately my supervisors habitually leave out this information.
Is there a way to make the Additional Request Details MANDATORY fields that must be filled out for all web-based service requests?
Also, is there a way to include this information in the work order notifications that are being sent out by the system to notify technicians that they have been assigned a work order?
