Please add the game number under the Official's name in the ArbiterGame payment screen. This is a very helpful feature that is in the A1 payment screen but not the AG payment screen.
Please add more details
This feature is very useful for schools when they are trying to figure out which game they are paying for or for a quick and easy unique identifier. The same reason it is used in the A1 payment screen. This could prevent incorrect payments. I have attached a screenshot of both pay screens. You will notice the game number is underneath the official's name in the A1 pay screen.
