Make it possible to remove certain spin projections from the initial state, just like in QRules+AmpForm (rudimentary form of spin density matrix). Case in point are the $J/\psi$ decay examples (J/ψ → K⁰ Σ⁺ p̅, J/ψ → π⁰ π⁺ π⁻, and J/ψ → φ(1020) π⁺ π⁻), were we do not want an initial state with helicity 0.
