Retractable cover for the cargo area?

Does anyone happen to know of a retractable cargo-area cover that fits a Prius C? I know the car has the hard cover, but since we often have items that are taller than the cover, it's become a slight hassle to keep taking it out and putting it back in. If there was a retractable one I could install and just use when needed, it would be much more convenient.

I've looked around online and haven't found anything yet. Anyone have any ideas or tried this already?
