Need help with color tagging under quicklook.

[thetorque]

In Finder, I have a few photos I would like to go through. I hit space-bar to activate quick look and I use the arrow key to scroll through the files in the folder.

Now I want to be able to quickly Tag Red the photo that I want while keeping the quick look popped up.

I have tried a few solutions but none has worked. It would be great if someone and show me how to do this is Mojave.

Sincerely,
