JPTD Lead by Source Reporting Sales CRM Reporting

We would like to change the Lead by Source Reporting to report off of the Appointment Due Date instead fo the Appointment Created Date.

"I was working with a dealership on lead reporting. We were using the Lead by Source report by salesperson. When you run this report and look for appts, the appt is looking at the date the appt is created versus the due date of the appointment."

Example:

Sales Appointment shows up in March reporting as the appt was booked on March 31st, but the appt was scheduled for April 1st (due date).
