Is there any way to enable the "natural" scrolling in Lion for the trackpad, but enable the "reverse" scrolling for a plugged in USB mouse? I've already adjusted to natural scrolling, and in fact prefer it, but on my mouse, not only is "reverse," or the normal method of scrolling, much better (for me), but I'd rather not get used to using a mouse the wrong way when all Windows PCs and work computers I'd have to use scroll differently. I tried looking in BetterTouchTool but that does not work. And while in preferences, there are two differently worded checkboxes in the Mouse and Trackpad preferences that seemingly would allow this, they are linked, and checking/unchecking one does the same for the other. Thanks!
