Well, this is pretty embarrassing. I never realized that I could click on the administration window and use my password to actually create a schedule! So I created two other providers, one of which was a dummy Doc where I listed all the walk-in patients. This would simulate a real day in the office, with two doctors and the list of walk-in patients. Fortunately, the optional "comment section" came in handy, because I could just type in WI and the time that the patient registered. I also gave every walk-in patient, a five minute time slot. Those two things helped to make them stand out in the schedule. The only thing it seemed that I couldn't do, was to drag and drop a walk-in patient to one of the providers schedules. Whenever I clicked on the walk-in patient, the other windows closed. It seems the only way I could get it to work was to click on the walk-in patient and actually just reschedule them to one of the other providers. A couple of extra clicks, but not too bad.
Does anyone see an easier way for me to do this, since most of you have been using the scheduler for a longer period of time?
