Auto-Reply to a 1-to-1 chat with the Outlook Auto Replies (Out Of Office) message

Today, the integration with Outlook allows Rainbow users to indicate they are Out Of Office using a little icon that appears next to their names in the Rainbow Contacts list. Other Rainbow users must hover the mouse over that little icon so that the OOO message pops-up and be able to read it. It would be nice if Rainbow auto-replies to an incoming IM in a 1-to-1 chat session with the OOO reply message that's set up in Outlook.
