How to see total ad revenue / unity balance?

So I made a simple game in April and I had about 15 dollars in revenue by the end of may, but since you are limited to going back 6 months in the ad revenue screen, I am no longer able to see the total amount of money I have earned through ads. I have been searching for hours for some sort of total ad revenue or total balance to easily see the total amount I have earned from the game.
