Tagging files within folders with certain tags

I'm using Hazel to help me implement GTD on my Mac. I have several folders that are "inboxes". For example, "Downloads", "Inbox - Video", "Inbox - Photo", "Screenshots", etc. These folders are tagged "Inbox". I want Hazel to tag the files in these inboxes "To Organize" so that I can search for all my files tagged "To Organize" when I'm ready to process them.
Hazel doesn't have a way to select the contents of a folder tagged something. I'm wondering if there's a way to add this functionality.
