Is there another way button to program for power?
 

I have a case on my TP and i find it difficult to reach for the power button on the top because of the way the volume and power buttons are 'inside the groove' of the case. But, what im asking, is there another button I can program for Power? I know I remove the pen and doing it, but I need a quick way from one of the buttons on the front. Any ideas?
