Feature Request - Auto flip through box/cart/cd art

I have X on my controller (xinuput) to flip between the box, cart, 3d box, cd, back of box, 3d cart.

I run everything in wheel mode with video preview and text on the right - I'd love for it to scroll (flip?) through the images every second or so (using slider in millisecond like attract mode) to show off the art. I imagine it could be part of attract mode first but also a general overall setting.
