CloudFlare Origin CA - Change Common Name

We are trying to upload a CloudFlare Origin CA ( to a managed cloud provider that hosts our applications and load balancers. The load balancers terminate TLS so we are trying to upload the CloudFlare Origin CA Public and Private Keys to it but it doesn’t allow us to upload since the CommonName (‘CN=CloudFlare Origin Certificate’) since it’s not a valid DNS name.

Is there any way to force generation of this Origin CA certificate but with a valid DNS name? (If not we’ll need this provider to either support CF Origin certificates or use a normal cert with a standard CName).
