NIS 2012 Restarting pc for updates

Is there any way to change the length of time that NIS 2012 allows you to postpone restarting your computer for updates? Currently it only goes up to 4 hours, and thats just a pain in the butt when it restarts while i am asleep or out of the house. So is there a way to increase the time to postpone the restart so i dont have to do postpone it every 4 hours until i am ready to actually allow it?
