I was setting up my Lan when I saw a dropdown list to select a group for a specific Lan setting. I can see that there is only a group to select, called default. This would be a great feature to have, since it would allow me to differentiate the devices by groups. So, I went to search inside all the admin web pages of the router, I even read the user manual (the picture below is from the manual) and there is no option to add new groups. Is this normal?
