Look for file in directory with specific name

My Rule looks at a main folder (Movies or TV Shows).
I want the Rule to look at the contents of subdirectories it's going to process and look for a specific filename in that directory.
I can't seem to find out if that's possible or not.
The filename will always be the same for the Rule, so I don't need to match any partial text.
