Run rules *only* on certain subfolder?

I have a folder called Daily Videos, and inside I have a folder for each daily video I shoot (Dogs, Cats, People). Inside each of those folders, there's an Original Footage folder that I put audio and video files into. What rules do I set up on Daily Videos so that any files I put into Cats/Original Footage will be renamed Cats.mov and Cats.wav, or any files I put into Dogs/Original Footage will do the same? In this image, I want mov_14.mov and wav_55.wav to be renamed Cats.mov and Cats.wav, and if I put another .wav then Cats2.wav. Same thing for any other folders I put into the Daily Videos folder.

Thanks!

Thanks!
