How can i reset my notification center preferences?

I am trying to reset all the settings under the menu 'Settings > Notification Center'.

For example if i customised the Mail notifications so that it didn't display an update when i got an email, i would like to reset this. However i don't want to have to manually reset each app which i customised the notification settings for induvidually.

I have looked under Settings > Notification Center there is no option to reset the settings to their default values.

A restore would wipe my phone, which is why i do not want to restore my phone, i want to just reset my custom preferences for the Notification Center.

There doesn't seem to be an option to do this.
