I don't believe so. I could be wrong (I have an EM-5), but I believe there's only three dials: the mode dials and the two scroll dials. The mode dials determines what the scroll dials will do (although they can be programmed a bit in the menu). There is a selection in the menu which will return menu settings to the original default.
The OM-D cameras have what is largely a programmable interface, which makes a lot of sense in a compact camera, as real estate on such a device is precious, and you don't want to force users to have a control they're never going to use. But the flip side is that if you have to get into the menus and actually program them by hand (or live with the defaults, whatever those happen to be).
