It would be nice if you had the balance owing refundable on that screen for earn taxpayer prior to transmit. That way I can confirm that the T183 form ties in before I hit the transmit button;
After transmit it would be nice if the transmit successful box included the same details as the transmit individually. (actually I really only need to see the three digit code i.e. 180)
That way I can see if I can expect any issues with the return from the family transmit screen and do not need to look at each individual taxpayers transmit screen
