Add more Power Management Options to Collections
Currently the number of power management options available on collections are limited to what SCCM displays but there are more options available to clients, either expand what is available in SCCM or make it possible to add new power options using the guids for those options.

Please add the ability to change the System Unattended Sleep Timeout. Default is two minutes, and there is no way to change this from the SCCM power options.
