show only major planet orbits in Solar System Observer mode?

Is there a way to show only the eight major planets (and their orbits and markers) while in Solar System Observer mode? I use Stellarium in my Astronomy class and showing the Solar System from above is useful, but the clutter of dozens of asteroid orbits obscures things. I know I can choose a different color for the major planet orbits, but that's not enough - I want to suppress the display of everything except the major planet orbits while in Solar System Observe mode and can't figure out how to do it. I think this used to work in older version of the program, but I'm not sure. I'm using the latest 0.90.0.9808 trunk version. Thanks.
