SSL Profiles Part 9: Server Authentication

Is there a way to set the Authenticate Name in an iRule? I ask as if I have a single virt setup to handle SSL connections to servers with valid CAs, I would have to have a Server SSL profile for each rather than a general purpose iRule. My goal is to use an iRule I wrote that takes cleartext from the trusted path behind the BigIP and then it encrypts the session with SSL/TLS. But when I set the virt to use the ca-bundle, I still need to set the Auth Name. From what I see, if I leave that blank, I might as well use IGNORE.
