OMSA Web Server launch using FQDN

Can OMSA Web Server shortcut be configured to launch using the FQDN rather than hostname? I want to replace the certificate on OMSA and use the FQDN but the Server Administrator launches using the hostname so I get an error message that the certificate isn't valid.

Is it just a matter of replacing the shortcut with a link using the FQDN or can I change something in the OMSA Web Server that it'll launch using the FQDN?

Thanks
