I am trying to have patients wait in a waiting line (taken from queuing location in library) in front of check-out desk when it is busy. However, the patients who have to wait then won't go to the next step in the patient track. The ones that have to wait in line keep saying "waiting for room" after they do check-out. I set the patient track as "first available" for the patient destination when going to check-out, so it is check-out desk first and then the waiting line if the desk is busy. Is there another way I should use the queuing line so it just temporarily holds the patients?
