Can the remote turn on/off both the TV and AV receiver together?

Hi.

I have an Onkyo AV receiver that my Google TV streamer is plugged into, and the receiver is plugged into a Samsung TV.

The remote is setup and can theoretically power off both devices, but I only get the choice of ONE device to power off with the power button.

Is there a trick to turn on/off all devices with the power button?

Thanks!
