Can I modify a TLE?

    Hello,
    
    I want to use a TLE with a ground track program like Orbitron to simulate 
    the path that a satellite takes when it passes directly over the launch 
    facility from which it began its journey at Cape Canaveral. Should I try to 
    find an archived TLE or can I simply change the Epoch Date and Julian Date 
    Fraction to a certain day to make the pass over that location? [I doubt it's 
    that simple.] If that is what I should do, for the ISS and Hubble, what 
    times and dates should I aim for? It doesn't have to be precise. I just want 
    to show students where the Hubble and ISS go after they pass over Cape 
    Canaveral.
    
    Because the inclination does not change, for an ascending pass, the path it 
    takes toward the zenith over one particular place would always be the same, 
    right?
    
    Thanks ahead of time!
