Notification on watch when disconnected from phone topic

I've used Tasker to alert and lock my phone when my Moto360 is not connected, and unlock it when it is. What I also want to do is display a message and vibrate on the watch when the connection to the phone is lost. I know there's an app to do this, and I'll go that route as a last resort if I have to. I have a GS4 so no Trusted Devices option like on some of the Motorola phones. Is what I want possible with Tasker or something similar?

Thanks,
Rich
