AutoNotification Block more persons notifications

I can block persons in messenger bij the option Block By Title. I can give in the name of the person and this is blocked. But I would like to block more than one in messenger. When I am at work I don't want my kids to sent me messages. So I want to block them together with some friends. When I amleaving my office I will unblock them again. But how can I block lets say 5 persons from my contacts.

 

I found it! It can be done with Regex support. For exaple to block the names Peter and Theo the title filter would be (Peter)|(Theo). So this can go to solved.
