How to Set HyperV NIC in Promiscuous Mode

Is there any way to set up a NIC on a virtual HyperV guest in promiscuous mode?
I want to try and run a web filtering product on a VM. Wireshark does not indicate that it is capturing all traffic.
I have my switch port mirrored already and it works with a regular box but not with the VM.

Any help would be appreciated.

Thanks,

Andy
