The EFFECTPLOT statement supports the FIT statement, which is used in this article. The AT option was used to specify values of the angles, like this
effectplot fit(x=Shot_Distance) / at(Angle=(120 60 150 30 180 0));

If your model has a CLASS variable called C with the values that you mention, you could use
effectplot fit(x=Shot_Distance) / at(C=all);
or if you only want a few levels, specify the levels like this:
effectplot fit(x=Shot_Distance) / at(C='AB' 'BC');
