You can change the date of service.
You could also create a note containing the patient's data, along with any questions you plan to ask at your first encounter, then SIGN OFF on it. Put "Pre-visit documentation" as the chief complaint, so your staff doesn't get confused.
When they come in for their first visit, pop open a new note. All your signed-off data will be carried forward to the new note. The date of service will automatically be correct.
If they "No Show", just mark that in their yellow Reminder field of the demographics sheet, so it will pop up the next time they want to make an appointment.
