appSwitch usage
I want to use appSwitch to create three separate switches (for HDMI 3, AV 1, and Live TV) so I'm declaring this in my config
```
            "appSwitch": [
                "com.webos.app.hdmi3",
                "com.webos.app.livetv",
                "com.webos.app.externalinput.av1"
            ]
```
Should that work? I only see a single switch in Home app, displaying all three items comma separated. Pressing the switch changes the input once, but does not cycle through.
