Default How to turn off 4.2.2 to 4.4 update nag screen

Given some of the issues I've seen listed regarding 4.4 on the Moto X, I've decided to wait until a point kitkat release comes out before going there (also if I decide to unlock/root, 4.2.2 is a better place to be). The only issue with waiting is the nag screen which comes up asking to update, and if you say no, you have to input a time for the next nag to appear. This is a T-Mobile version. Is there any simple way to have it stop asking to update?
