Thanks Sandeep. I was looking for a way to re-assign items that have already been accepted, so no longer in the agent's inbox.
I figured out how to accomplish this. I set the condition on the channel to "Assigned to is empty", then created a business rule. When agent availability (table is agent_presence) changes to "Offline", it will query all open cases assigned to the agent and update the assigned to to empty. The AWA channel will then process the case again for assignment.
