public static class Example
{
    [MenuItem( "Tools/Hoge" )]
    private static void Hoge()
    {
        var path      = "Assets/Transform.preset";
        var preset    = AssetDatabase.LoadAssetAtPath<Preset>( path );
        var transform = Selection.activeTransform;

        PresetUtils.ApplyToWithExclusion
        (
            preset,
            transform,
            "m_LocalPosition.x",
            "m_LocalPosition.y",
            "m_LocalPosition.z"
        );
