GPS Toggle

In the never-ending quest for better battery life, a common suggestion is to turn of the "My Location" setting on the device. It is my understanding that this in essence turns off the GPS functionality of the device (please correct me if I am wrong and this does something else) so whenever you want to use a program such as TeleNAV or Google Maps with GPS you need to navigate to these settings and turn it back on. Is there some program that exists that does these simple changes? It would be nice to place a shortcut to such a program right next to the GPS related ones so its not such a pain to enable. Thanks!
