Have AlertSite monitor API's that use Kerberos Authentication

I have an API in ReadyAPI that uses Kerberos Authentication. I worked with SmartBear support to get it working via these steps: https://support.smartbear.com/readyapi/docs/requests/auth/types/spnego.html. I get errors when I upload the API to Alertsite as a monitor, because these same changes need to be made to our private node in order to run, which is not available. We would like it to be possible to run this web service as a monitor on our private node in Alertsite.
