$HOSTNAME does not return full PC name

[abramesd]

I am using a Sensor Panel and I want to get the full name of my PC.  The Label variable $HOSTNAME does not return the full name of my PC.  When I look at the Computer Name panel in the AIDA64 main app I can see the full PC name is several values. Is there a way to create a new "$variable" for the label or to change what $HOSTNAME returns.

I have the AIDA64 Extreme version
