There is a second reference field when posting invoices which we use to enhance the invoice number by defining what it the invoice is for like ACC21 / PAYQ4 / BKSEPT21 etc. but we can't add it to the VAT receipt template, or the statement template and it doesn't appear on the billing decision report in the previous bills listing, we can only have the first reference field . Can the 2nd reference field be made more widely available so we can benefit from using it to add detail to the invoice number?
