USB 3.0 Male Header to USB 2.0 Female Header?

[Rapter12]

Hello I've been looking for a USB 3.0 Male Header to USB 2.0 Female Header for my mother boards cause I don't have enough usb 2 headers on my mobo, but I do have an usb 3 header that I'm not using on it and I don't want to rout the USB 2 header through the back with a USB 2 Header Connecter to USB 2. Just want to know if there's anything out there that's like that, if not I will just have to got through the back then.
Any Info will Help
