Changing Mac Computer Name Entry in Sophos SafeGuard Server Management Center

Hello,

I'm not using AD integration with my SafeGuard Management Center instance. When some of our macs get encrypted they happen to have been on VPN when they register with the server so their names appear as "asa-vpn-324343" instead of the computer name that appears System Preferences -> Sharing. How can I edit the database entry or update the name in SafeGuard Management Center. It makes it very difficult to support these machines because their names aren't accurate and the webhelpdesk can only use computer names to look up clients. Any Ideas? Thanks
