[HTC Vive] Screen is always on when using UE4 editor, is there a way to turn it on only when Playing in VR?

The screen on the HTC Vive is constantly on, displaying a gray solid color, when I’m using the editor. The device gets really warm because of this and I feel that this wastes energy and could impact the durability of the device itself. The button on the headset doesn’t seem to do anything.

Yes please fix this!
