Accessing Headers/Response on Execptions

Is there a recommended method for accessing the response and/or response headers for calls that trigger exceptions? I was looking through the DropboxRequestHandler.cs file and it doesn't look like any of the values from the HTTP response are passed along into the exceptions that get thrown (RetryException, BadInputException).

It looks like the RateLimitException does a nice job of passing back along the Retry-After header as part of the structured exception. I'm looking to read the "X-Dropbox-Request-Id " and "X-Server-Response-Time" headers in my exception handling code.
