HTML5 Canvas: Publish images without creating an image folder

We use Animate to create animated digital ads in HTML5 which we publish, compress and send to a vendor. Our vendor this year has decided that our images cannot be in a subdirectory; they must be in the main folder with the other assets (HTML file, javascript file). I have looked a the Publish Options in Animate and I am able to change the name of the images subdirectory but I don't seem to be able to remove it or change the destination that images are sent to; does anyone know of a way to publish through animate and have the images placed not within an image folder but with all of the other assets in the main directory? I'm really hoping that there's a solution here that doesn't require me to go in and change the code on the published files.
