Release : 22.2
You can't change the Author of a Certification and you can't extend anything except a CA Certification.
All custom certs are direct PUTs to the /typecatalog/certifications/snmp/<certname>.
There is no need to extend something created/maintained by the customer. The purpose of the extension is to allow the OOTB VC to be changed and take in the new changes to the base VC during upgrades.
