A few ideas:
1. On days when you want to schedule an appointment, right click on the bar at the top, and enter a note (e.g. "John Smith 6PM". This will appear in yellow at the top of the day's schedule.
2. Use an extra slot at the end of the day. So if the last patient is seen at 4, in the 4:30 slot, put "Pt from old office" (there are a couple of ways to put that in the slot).
3. Create a new provider: "Dr. Afterwork". Use Admin options to set the possible hours patients will be scheduled. The appointments will show on a second schedule (the one for that provider)... but they only show up on days when an appointment is scheduled; otherwise, you won't even know the schedule is there.
