How to get TV server to wake up when watching TV?

I have a seaprate box with MediaPortal TV Server installed. It wakes up only when a client machine starts up MediaPortal or when a recording is scheduled. However, on my HTPC I have Kodi with the MediaPortal PVR Client plugin installed and I can’t see any way to configure it to wake up the TV server when clicking “Watch TV”. Am I missing this option or is it not implemented?
