Suggestion for extension of controller

Hi Insite...thanks for the answer.
I look at the Filter official documentation, but if i correctly undestand, i must declare EACH my controller in the route file with the right filter. Is correct?
In CI3, in that mode, was very simple: if i wnted chech logged, i extended the logged Controller, if admin, i extended the admin controller ecc.
An other thing: in that mode was very simple to manteinance.

Is it possible recreated the same solution with ci 4?

Thanks for the answer...
