Capturing response headers when using REST task

I'm attempting to setup a Botflow to interact with a REST service. When passing the initial credentials to the logon endpoint, the service will send an authentication token in the response header (which is different then the response content). 

Is there a way to capture the header response in the REST task? I see the content and status code can be saved, but not the header.

I took a quick glance at the Workflow product and see that in it's "Call a web service" task it's got an option for the response header... just need the same thing for RPA.

Thanks!
