Certificate Management: CA certificate upload.

Looking at the latest certificate management schema( DSP2046 Version 2018.3), not seeing any url's related  to well-known public CA certificates.

Any work is in progress related to this or am i missing some thing here ?

/redfish/v1/AccountService/Accounts/{ManagerAccountId}/Certificates/{CertificateId}

/redfish/v1/AccountService/ActiveDirectory/Certificates/{CertificateId}
