I am pretty sure you’re referencing the comments plugin thing (what we typically now just call “chat”). Sadly, that is not really possible at all, since the tags are solely dependant on IP Address, and on most devices, they have something called dynamic IP, which cycles their IP every so often (for that single location.), or their location changes and they get a new set of IP addresses they cycle through then. So, for short, I doubt that that suggestion will be added, let alone be possible from the developers side. (You can do it my changing your IP to a static IP, but then you’ll be putting yourself at risk because now your IP address wouldn’t change (if set to static), and it would be easier to hack your device.

Hope this explains it :D
