If your only objection to AC's suggestion is that your mailbox will become cluttered, then consider forwarding the encounter to the Nurses or Providers inbox. Then when you have someone whose info has already been entered just look for it there. Click the Patient Name bar at the top to order the list by name. You will probably have to change the encounter date to the date they're seen though.
I believe that will work fine.
But, I think it's generally a bad idea to let your main list get too long and AC has said they suspect full inboxes are related to the problem with AC dropping some connections. Just so you have an idea if you start to have problems. AC might have another point release before that happens though so just keep it in mind.
