I'm trying to track customer payment behavior over two different time periods, and I'd like to calculate the average time to pay from one period (Sep 2021 through Mar 2023) and compare it to another (Apr 2023 to present).  However, when I use the average time to pay report in Quickbooks, all that comes through is the total average time to pay for the customer, regardless of what time frame I band it to.  Is there a way to view a customer's historical average time to pay, or will the report only ever pull their present average?
