Aha/Rally Feature mapping for Refined status

We currently have no way for Rally to tell Aha that a feature is fully groomed.  This would help considerably to give Product team visibility to the feature grooming status in AHA for PI Planning and priority alignment.  Aha has a feature status of Refined but Rally does not. Rally tracks the completed feature grooming with a check box of Done rather than an option in the status dropdown.  Can the Aha Refined status map to the Rally 'Done' if checked or can Rally add Refined as a selection option in the status field that can be mapped to AHA?
