setting NIC display name with autounattend.xml

Hi there,

in earlier version of unattend it was easy to set the NIC setting. Now with
WSIM, how can I set an NIC display name, to rename it from "Local Area
Network" to e.g. "Heartbeat".

Also how do I identify a NIC in autounattend.xml? I know that I can use the
mac address. But I don't want to use mac addresses in the autounattend.xml

any idea to both of these questions?
