Peer references are now associated with an appointment term in Silversheet. You can add peer references in the Obtain Peer References step in the appointment. Peer references can be configured differently for an initial appointment or a reappointment.
TIP: If you don't require peer references for a reappointment, go to Settings > Peer References and set the number of required peer references to zero. The Obtain Peer References steps will no longer appear for reappointments, but will be available for initial appointments.
