Wayne:
I suggested above that you could create a custom phone list of your referring physicians and keep it in your Letter Writer, or something like that. Anyway, I just thought of a shortcut you can use to create that list.
Just go to Administrative Options, click the Import/Export tab, then click on "Export Practice Rolodex". This will create an Excel file with all that data in your Amazing Charts folder.
You can edit the list in Excel, or, if you are not big on Excel, this can be imported into Microsoft Word without opening it.
You can then massage the list into a format you like, then copy and paste your demographic list into a template in Amazing Charts.
Hope this helps!
