Bleach Jug sizes now available in 121 ounce volume

[dr2casto]

I am able to buy bleach in 121 ounce size containers now from local retailers. I also noted that in the PoolMath FC portion of the test, the only selections in the drop down window do not contain this option.
Is there a way to modify or add it to the calculation drop down menu?

Also I am unable to add an attachment here?

121oz is available on the Pool Math drop down menu. It's the last option
