Generate report of patients with outstanding invoices

It would be extremely useful to be able to generate a report with the names of patients with outstanding invoices.

We invoice insurance companies at the end of each month and being able to generate a list of patients with outstanding invoices rather than manually going through the outstanding invoices report would help speed up this process. If we could filter this report by month it would make invoicing easier as well as chasing up overdue invoices.

Being able to customise the emailing of account statements the same way we can customise the emailing of invoices (ie. edit email subject, text etc) would also be very handy and help streamline the invoicing process.
