You will need to install a user script manager extension to install this script.
This script will hide the instructions but you can click on the instruction text to show the full instructions again. You will see 2 buttons at the top of the receipts for easy access. If the receipts are different then click on the first button. If they are the same then click on the second button. Once you push a button it will fill in the bottom radio buttons and submit the hit if you checked the checkbox called submit after. By default it will not submit after so you have to press the submit button or press enter after the submit button gets focused. You can also use keyboard shortcuts to make it easier. Keyboard shortcuts follow the submit after setting so be careful. Pressing n or 1 will select the no option. Pressing y or 2 will select the yes option. Then you can press enter to submit the hit or click the submit button if the submit after option is off.
