Display "Payment History" on the emailed Order/ Invoice

The Order/ Invoice needs to show the complete payment history on the rendition of the order that is sent to the customer so the customer can reconcile individual credit card payments against the order/ invoice.  Currently, it only shows the total of the payments.  

I have a school district customer that requires that all credit card payments be reconciled against the order/ invoices they were sent.  When an order/ invoice receives more than one payment, the individual payments are not displayed on the their copy of the order/ invoice.  It only shows the total of the payments, which does not give them the detailed information they need to reconcile the credit card payments.  

The software should be smart enough to provide them with that information by default instead of them have to call me and have me email them a screenshot of the their payment history.  This is a feature that is greatly needed.  Thanks
