How to invert adblock or ublock extension work?

Question

Ad blocking

I faced the problem that on many sites more than 20, sometimes even 40% of the screen space is banners of different sizes, as well as ads embedded under the design of familiar content.
For example, these are: message boards, or YouTube, which considers it quite normal to show 5 different banners with an interval of a second every time you click on the cross.
I don't need to block all ads, as I myself am from the IT industry and it is important to observe trends and changes in order to respond quickly to them.
But when it comes to ordinary tasks, and you are faced with the most inadequate way to display ads, you want to close such a site and not open it again.
There is a solution, to launch the blocker, but, for example, in the Chrome browser, it takes several steps to do this, and in the latest updates, the usual hot keys for opening frequently called tabs were turned off.
Now just enable and then disable the extension - a task that requires more time and attention. And so I'm looking for a solution in my question, how to make the ad blocker work in inverted mode?
How to make it block only ads from those sites that are in the desired list.
