The easy way to solve this is an internal usb hub with headers. I would say get Thermaltake's H200 Internal USB Hub but they are out of stock. So what I got was Nzxt AC-IUSBH-M1
I had to get it for sort of the same reason I have 3x riing plus control boxes plus front usb ports and only wanted one header in use on my motherboard. To make it look clean as its is easy to hide with internal hubs.
