First, the only Fuji that has a "super control panel" type of interface is the X-Pro, which has a "Q" button that brings up an essentially identical screen.
Second, the EASIEST way to use EXR on the X10 without surrounding total control of the camera is to set the resolution to medium (ie, 6mp), set DR to AUTO or AUTO 400 or whatever its called, and AUTO ISO with whatever high end control you're comfortable with. Then just shoot in aperture priority or shutter priority or whatever and control your favorite variable, and the camera will do the same EXR calculations for both DR and low light but you still get a modicum of control. Try it and do some back to back tests with AUTO EXR and I'll bet you won't see much if any difference in the settings it chooses.
Have fun - great little camera...
