Oribi Need FW update to block internet access without killing Network access

Currently, if I pause the Internet for a device through the NETGEAR Genine it makes that select device unavailable to my local area network.

I would like to request a firmware feature to block specific devices from going outside the local area network. I have many devices on my LAN that do not need Internet access, but still need to function on my LAN as a network device. Have WAN access should be a ON/OFF option for a device in the phone App, as well as the browser interface.

Thanks
