Pre-defining Settings
Before you start adding mobile devices to the system, you may want to take the time to pre-define certain settings so that they can be easily applied and edited when the time comes. Note that these procedures are optional–if you do not pre-define options for a setting, you can still define those settings manually during group creation (except HTTP proxies and Wallpapers)–but they can save you time if you are deploying a large network of mobile devices.
Note that you can edit pre-defined settings at any time. Changes made to a pre-defined setting are propagated to all groups using that setting.
