Add "Exclusions" to WWW Session Proxy Configuration

We have a hosted SaaS product that we must connect to using the organization's proxy server. However, in order to login using using SSO, we must be able to connect directly to our IAM hosts. This is easy using any browser's proxy settings by adding exclusions for "sso.example.com" or "*.example.com". This option is not available in the WWW Sessions proxy configuration. As a result, we are unable to use RDM to connect to this externally hosted SaaS application. Hopefully this isn't too difficult to implement because this would be tremendously useful for this, as well as other connections I can see wanting to add into RDM.
