‘Supersymmetrizing’ an arbitrary quantum-mechanical potential


To my understanding, it is not possible to \text{supersymmetrize}" an arbitrary quantum-mechanical system unless one knows how to represent the corresponding Hamiltonian in the form H = A^\dagger A \quad, which can be as difficult as solving the Schrödinger equation. (I guess, in QM we can generate SUSY potentials by playing with arbitrary superpotentials W(x).)


So, I realize that my question is not very rigorous. Anyways,


Is there ANY way to construct a supersymmetric Hamiltonian H_S from a given one, H? (without the necessity to solve Schrödinger equation for H or doing some equally hard things)


What I mean here by \text{construct}" is not necessarily what people typically mean by this word in SUSY QM (see e.g. here). The only thing I want is SOME SUSY potential whose construction would somehow involve using H.


P.S.


Note that we know how to \text{supersymmetrize}" nearly any field theory. This suggests that a similar thing should be possible in QM.
