Brave News Feed - Customizing & Blocking

I have taken a lot of time to customize my Brave newsfeed. However, there are always other publishers in my feed that I have no interest in. It’s annoying me enough to consider not using Brave. How can I ONLY see the publishers I have chosen through customization?

Especially when there is a SUBSCRIPTION required. Telegraph, Barrons and the New York TImes, for example. It wastes my time to click on articles from those sites.
