Could you please tell me if this is possible to do?

Thanks!

I have two combobox in a Browser Dialog "Customers" and "Building Address".  The records in the Building Address should be filtered by the selected Customer. 

I have done this for the maintenance form, but I have not find a way to have the combo filtered in the Browser Dialog (BD), and the events exposed to the BD does not allow me setup code to Requery the BuildingAddress BO.
