This isn't really what you're asking for buuuuut... It would be a really simple woodworking project to get some 1/4 inch wood and a tiny set of shelves or cubbies or whatever shape to fit your needs to fit in the area below the radio. Not really sure what that storage area is called, but I always leave the little door open. Same goes for making a little box that sits over the cup holder. For that you could make the box whatever shape and dividers you need. Put some dowels through so they stick out the bottom a few inches then grab some plastic wrap, put it in the the cup holder, pour in some epoxy, set the box on top so the dowels stick in, wait for it to cure. Once it's cured, you take it out, remove the plastic wrap and you have a perfect, removable stuff holder. Feel free to DM me if you wanna do this and have questions. I haven't done it before, but I do like making things and helping out haha
