We currently have a field that is title "start session". We then customize the dashboard to view how many student are in a session. At first this method worked perfectly. As time went on student would re-enroll at a later time and in order to capture them in the current session we had to change their "start session". Then when we went back to view our fiscal year the number were always constantly changing. Is there a way I can program Saleforce to allow me to customize different school years/ lead?
