This procedure makes full use of the close connection between QES systems and supersymmetry. Of the ten classes of $sl(2)$-based one-dimensional QES systems, we have found that nine classes allow such construction.LaTex, 20 pages, no figuresHigh Energy Physics - TheoryMathematical PhysicsSpectral TheoryExactly Solvable and Integrable SystemsQuantum Physicstext
