[Plugin: Advanced Custom Fields] Category Images

I was hoping to use the ACF plugin to get this behavior.

I would like to set 1 or more images for each post category and then when the user is creating a new post and they select the category(s), the associated images are displayed, allowing the user to select one… sort of like a featured image, but a little easier for the user as the images have been predefined for each category.

I created a custom post type “Category Image”, which allows the user to upload a image against a category and then was using Advanced Custom Fields to pull in the custom post type… close, but it needs to dynamically filtered by category, and I would also like to show a thumbnail or preview of the image.
