I have a form that collects data on a doctor's patient evaluation.  The Evaluation table (and associated BO) only stores the primary key for the doctor in the Doctor table.  The user selects the doctor's name from a dropdown list (PopulationType = BusinessObject) that is populated from a business object mapped to the Doctor table.  I need to create a browse dialog for the Evaluations where one of the search fields is the doctor's name but the only data pertaining to the doctor in the Evaluations BO is the doctor's ID in the Doctors table. 

How can I make doctor name one of the searchable fields in this scenario?  I looked at PopulatedThroughEvent but I don't think that's the ticket.
