One thing that is often tricky when you have a lot of uploaded art assets, is knowing which of them are actually in use. I suggest adding two automatic indicators that would appear on each piece of art in your library: An indicator to show the art is used in THIS campaign An indicator to show the art is used in ANY campaign You'd never have to show both indicators: if the first is true, the second is also always true. You would only need this indicator for uploaded assets and not marketplace assets.
