2015 Prius can I use a USB Port or something for more audio USBs

I can play music through a USB port in the between seats storage unit. I can charge with a console cigarette lighter-style plug. But the 32GB limit on USB drives is starting to bug me (since the main collection I want to play has grown to 34GB), and I'd love to have more than one kind of playlist available at a time.

So is there any way to connect more than one USB drive using a USB Hub or something?

No harm in asking.

Regardless, still love my Prius ... best car I've ever owned.
