In Quickbooks Online, how can we get our "Account No" from Supplier Details to appear on the Remittance Advice form?

Most of our suppliers have assigned us an Account Number. We need this account number to appear on every Remittance Advice form that we send to our suppliers. In the "Bill Payment" screen, when you click "Print" at the bottom of the screen, the resulting Remittance Advice form does not include our Account Number for that supplier. How can we add that field to the Remittance Advice form?
