Button to not accept SP?

Hey!

I saw that today the 2x SP week thingy started. Now this is great for alot of people I guess but not so for me.
Call me selfish or whatever you want, but shouldn't there be a button for people who want to stay rank 8/9 or whatever rank and not earning SP at all? Like a button in the option bars in main menu where it says '' Earning SP [on/of]'' ??

As for this week I think im not joining any game xaxaxa or cw's . Rank 9 forlaif bitchaz
