Can we have a setting to control how often a device is trusted?

I love that we have the ability to secure our accounts with two factor authentication. With every website, game, and service I have an account on I enable two factor auth whenever it is an option. DISboards is the only one that prompts me for my two factor token every 30 days. Can you please consider either a setting to increase this amount of time? I find this frustrating and annoying.
