Reports- Payment plan info pulled to use workflow

It would be a good idea to have "payment plan number" as a filter for reports to generate.

That way we could use workflow to automatically send out invoices based on the payment plan number we are up to.

We would set up a template for "Payment plan one", "Payment plan two" etc so then when the report pulls anyone due to be sent an invoice for payment plan one, they will receive the correct template.
