What I have actually done is, since I have my own instance for just me, I created another account which subscribed to the communities that drown out the others, but then unsubscribe from them on my main account. That way they still get federated to my instance, because I want to see them sometimes. Then when I want to see those communities, I view All. And when I don't want to see them, I view subscribed.
It's kind of silly, but it's perfectly fine as a temporary solution.
