Controlling Atom connected to Arcam surround receiver

When watching TV, I have an Arcam surround receiver to do the digital-to-analog conversion and power the center channel, and then send the left/right channels to my Uniti Atom via preouts.

Right now, this means that to watch TV I have to turn the Atom on separately from everything else. Is there any way to avoid that (and thus reduce effort and remotes I have to fiddle with)? That is, when the Arcam receiver goes on, just have it auto-turn-on the Atom?
