Add new NIC to VM (like New-CINetworkAdapter)

Hi all

I'm trying to find out how to simply add a new NIC to a VM within a vApp.

Something like "New-CINetworkAdapter" would be great, but unfortunately does not exist..

Anyone some experience or tipps for me on how to add a NIC to a VM within vCloud Director?

Have already tried to create the NIC via New-NetworkAdapter in vSphere (which actually works), but then vCloud Director does not recognize the NIC and still thinks the VM has no NIC.

Thanks and cheers
