zero dollar payments

hi, I needed to give a group a 100% discount but want to create and invoice so we have a record of this.

THIS IS MORE A QUESTION/SUGGESTION FOR THE DEVELOPERS

unfortunately you cannot make a zero dollar payment even if the invoice says zero dollars owing. without "making a payment" the client still receives overdue invoices even though there is no charge.

I had to change the invoice to read that there was a one cent charge so I could "make a payment" so I could clear the open invoice.

why cant we have a zero dollar invoice and not have to leave it open?
