    There is something else you can do that doesn't get what you asked for but might 
    give you what you need.
    
    Go to the calculations tab.  You can select "all" satellites if you want.  On 
    the left side there is a choice "sat mag <".  Put your maximum magnitude here. 
    e.g. 4 will give you only very bright satellites.  Setup the dates and duration, 
    sort by rise time.  click 'begin' button.
    
    You might want to click 'clear' on right edge before clicking begin.  Now double 
    click one of the satellites in the red-on-black list of passes and it jumps you 
    to the 'sky' tab with the satelltie path highlighted.  Click on the double right 
    arrow to skip forward a minute and you can now hit play and watch that 
    satellite.  Try going to the "chart" mode at this time and use the "time slider" 
    feature to easily see with sats are LEO, MEO, GEO.  Go back to calculations to 
    select the next sat.
    
    If you only care about GEO and want brighter than a certain magnitude, then 
    instead you should use Greg's method but this requires knowledge of which are 
    the "brighter" sats.
