comodo API - auto approve renewal of a certificate.

Hello -
We are working with the Comodo APIs. For the most part, we have creation of new certs working pretty good, with auto approvals. Starting to work on renewals we are running into some issues. We can call the APIs and issues the renew, using the renewid and pull down a cert once it has been approved, but we are unable to figure out how to auto approve renewals. Is this possible?
