How To add a SubjAltName extension with a default CN value in caServerCert profile for Red Hat Certificate System?

Issue

Recent version of both Firefox and Chrome are saying a site is untrusted if the SubjAltName field in a certificate is empty and does not contain the name in the CN.
Is it possible to change the caServerCert profile to add a SubjAltName that matches the CN without having to add it manually when a user submits a CSR?
The behavior I would like to see is that a user submits a CSR as normal and the CN is added as a SAN to the cert without having to specify it in the request page.
