until then you can use the file export:
pstricks-add knows

\define at key[psset]{pstricks-add}{filename}{\def\psk at filename{#1}}
\define at boolkey[psset]{pstricks-add}[Pst@]{saveData}[true]{}
\psset[pstricks-add]{saveData=false,filename=PSTdata}

You can write the values into an external file and use
the values for a next run of \pstDiffEqn.
