How to add attributes NetConnectionStatus and NetConnectionID to Win32_NetworkAdapter Hardware Class

Question

We are trying to run SCCM (CM2012 R2) reports that show devices with an active network connection. I know that there is a WMI class, Win32_NetworkAdapter, that has the attribute NetConnectionStatus, which if it has a value of 2 means it has an active connection.
I can go into WBEMTEST on my Windows 7 (works with XP too) device, and can get directly to the Class / Attribute. However, when I go into Hardware Inventory (through Client Settings) and look at the Win32_NetworkAdapter Class, I don't even see this attribute
for me to enable.
What can I do? I'd like to start gathering this information during the Hardware Inventory Scans.
Thanks!

So based on what you are saying, we should create a new custom class? Say "Custom_NetworkAdapter" or something like that?
So basically import something like this?
[ SMS_Report (TRUE),
SMS_Group_Name ("Network_Adapter_Addtl"),
SMS_Class_ID ("CUSTOM|Network_Adapter_Addtl|1.0"),
Namespace ("\\\\\\\\.\\\\root\\\\cimv2") ]
class Win32_NetworkAdapter : SMS_Class_Template
[ SMS_Report (TRUE), key ]

[ SMS_Report (TRUE) ]
