How to allow all lower-level domain based on the second-level domain in uBlock Origin?

Question

Many sites have third-level domain: en.wikipedia.com, academia.stackexchange.com, translator.google.com. I have a universal dynamic filter:

* * 3p-script block

and would like to individually allow all domains from Wikipedia, Stack Exchange or Google to load 3rd party scripts. But it seems that dynamic filtering doesn't support wildcard on the domain.

Answer 1

Well, you can whitelist them. It even support regex.

Emphasis mine:

• example.com: whitelist all pages from example.com or above (i.e. example.com, www.example.com).

The downside is that you can't use filters to block ads on whitelisted sites.
