How do I isolate transactions that are part of a flagged set of patients?
Patient > "New by Month"

Enter a date range
Flag the found patients (in the list view)

Clarical > Stats

Enter the date range

Right click (CTRL click on the mac) the flag to "constrain found set" (bottom flag is the PATIENT flag, top one is the TRANSACTION flag)

There may be many transactions per patient. Flagging the PATIENTS you want first allows you to isolate those TRANSACTIONS that are associated with the flagged PATIENTS.
