PureVPN Device Segregation

Ok so I have seams some topics in reference to VPN services but it would be a good enhancement if the router can segregate which devices utilize the VPN connections and which ones are excluded in devices.  Right now, it is all or nothing approach. I would like to either setup a rule in which devices you require to use the service that is installed on your nighthawk netgear router or select all devices.  

I like the ability to segregate some of my streaming devices in which it will not use the service but all other devices on my network will utilize the VPN Service.
