Is there a way to set scroll direction independently for mouse and trackpad

I use multiple pointing devices, including a mouse and Apple Magic Trackpad, and it is very frustrating that it is not possible to configure the Mac so that both devices scroll in the standard direction for those device types.

There is a setting in OS X to reverse the direction of scrolling under System Preferences > Mouse > Scroll direction: natural, and also under System Preferences > Trackpad > Scroll & Zoom > Scroll direction: natural. But these both control the same setting, so if you change one, the other updates too.

For me, what's "natural" for a trackpad is different to what's "natural" for a mouse. I want a trackpad to behave like any other touch surface (drag the page in the direction you want the page to move) and a mouse wheel to behave like a mouse wheel (turn the wheel in the direction you want to scroll).

Is there an Apple-approved way to set these settings separately? Or a safe workaround for it.
