parental control block domain

Marmo

We have Bitdefender on our sons laptop. He needs the chrome browser to support the distant learning, we have found out that he is going to game websites like paper.io during class. Is there a way to add in the whitelist/blacklist an entire domain (i.e *.io) vs having to enter specific URLs to block?

We have the category GAMES turned on but that seems to let some things through when using a browser based game.
