Vizio TV driver missing source names

I'm trying to test the Vizio TV driver by changing inputs between HDMI2 to HDMI3 and as I'm using the driver command testing, I'm selecting the Source command and I see the Target Device and Actual Command example (which shows <family name>|<device id>~Source~Name).  After I select the device, I don't see a way to select the Source Name, like I see with the LG WebOS driver.  Is this something that's missing for the Vizio TV driver?

I tried to send the actual command of AV|2~Source~HDMI3 but it just opens the input menu on the TV and doesn't do anything else.

Thanks

Any chance of bumping this item up on the TODO list?  I can't do much if I can't change inputs.

Thanks

I see that a new Vizio TV driver was released but I'm still having issues changing the inputs.  When I select the Source command, I see the full command listed but then when I select the TV, the command seems to get truncated to not allow the last part.  I also tried entering an input at the end of the command manually, like so:  AV|2~Source~HDMI3

Is this something that is broken or maybe Vizio doesn't fully support this?

Here are some screen shots of what I'm seeing.
