Can I add a LAN bypass port to XG V17 Virtual appliance?

So i read that the new XG HW units now have a LAN bypass port available, so I want to find out if there is a way to add an interface on a Virtual Appliance XG v17 unit and set that up as a LAN bypass port?

Surely there must be a way to use the console to do this?  If it can be done i would be ever so grateful if someone could give me the procedure to set this up.

I know there is a way to enable LAN bypass mode in the console but that only works for Bridge mode if i remember correctly, but i need to use Gateway / router mode deployment.

Thanks
