Changing ratings for multiple players at once?

Is it possible to do this? For instance, I want to toy with certain ratings across the board to see if it changes the game. For instance, maybe increasing or decreasing offensive or defensive awareness for the whole league, to see if it helps your computer controlled skaters move into a good scoring position, or increases the chance of the computer scoring against a player, or making the computer defense better.

Messing with checking and fight ratings is another thing I'm curious about. It would be much easier to, say, click down once to decrease every player's checking by 1 step. Thanks
