Allow lockdown of ScreenConnect (SAAS) to a customers instance only.

Adversaries can use screen connect for command and control. When using ScreenConnect (SAAS) the client utilizes both shared and customer specific subdomain FQDN, this means you can't lockdown network traffic to the customers subdomain only as it would break the application. This feature request is to seek a method to lockdown screen connect via appropriate controls so only a customers version will work in the environment.
