Creating a macro for switching between headset and stereo, is it possible?

I recently got a razer keyboard with 5 macro keys, so i installed razer synapse and tried out the macro function. all i have managed to create so far is a macro for volume up and one for volume down, and assigned these to two of my macro keys. But what i really would love to have assigned to a hotkey, is changing default playback device, because i switch between them several times a day.

I do gaming on my pc monitor with a headset, and i watch things on my tv which is connected to my pc. and every time i switch to doing the other one, i have to go into playback devices and change which one is the default communication device.

Would it be possible to create a macro that i can assign to a hotkey, that does this for me?
