Plaxis LE coordinates of all slip surfaces

Dear Sirs,

I use Python scripts to connect with Plaxis LE 2D, and all the calculations are performed without problems. But when I want to get the results of all slip surfaces I encounter a problem because only the FOS and a maximum depth are given. Is it possible to get the coordinates of all slip surfaces (not only the minimum one) with python scripts? 

Best Regards,
