there is only one way to do this so that you dont have to keep retargeting specific rows or input/class names - remember these are dynamically generated at runtime and depend directly on the type of account you have (personal, business, educational, etc) as well as MANY other variables incl which features are enabled, even plugins integrated, etc.
Please see my post here for fully dynamic approach that will never need to be changed (or at least until gmail overhauls, etc):
