Question if a feature is possible

Would it be possible to add a feature to pi-hole that would tell websites that I am not using an ad blocker when I really am using pi-hole? I go to CNBC ,and other news sites, a lot and get that pop up asking me to disable my adblocker but for some reason it still lets me go to the site it is just a hassle. I wanted to know if pi-hole could stop that for me.

I found the answer in another similar question.. Not possible.
