Capture response date from proofing request

Content

When a proofing message is sent the date/time is captured for when it is sent.  But, when a response is received the date/time is not captured for that response.  The only dates that can be added under Options -> Field Chooser are "Sent" and "Created."  Need a "date updated" or something similar added to the field chooser to see when a response arrived.
