It would be great if you could run a report in therabill to list only patients who have not had a statment in a certain time frame. We llike to work on statemetns each week but not send a statement to all patients weekly. If the report would show only patients who have reveived a stmt greater than a custom time frame (30 dasy, 21 days etc), then we could send patient statements with better spacing.
