Something that would help out alot for these canvases, would be on the logo uploads (image placeholder) would be to have the ability for the customer to add multiple files under that same image placeholder. In my mind, it would look like this. Logo Upload with background remover, After you've added an image, it says replace. Below that, a box that says "add another image" or something like that within that original option. The only way that I could let the customer add multiple logos or whatever would be to stack several Logo uploads and the page would get cluttered.
