How to tag containing folder

Hello there. First time poster and new user. Loving Hazel so far!
I've created a rule to move a file, rename it, then tag it with an 'action required' tag. (works well)
I want the containing folder to automatically tag itself 'action required' when it contains a file with the relevant tag.
So I know there is a file waiting without having to go into the folder.
Hope this makes sense. I've been trying for about a week to find a way to do it!
Any help would be greatly appreciated.
