payment QR Bar Code should be of the total party pending payment

the QR generates with the bill is just for the current bill payment not for the full party pending payment . It should be for the total pending payment for the party as someone wants to pay his 5-6 pending bills at the last he has to pay every bill separately. It is difficult for the customer to pay every bill .

So its a humble request there should be an option for the one QR which shows whole payment at once only
