Synthesize Cauer-Chebyshev, Full Transform using S/Filter?

If you use the passive filter template in Genesys you can generate an N = 3  -  Cauer-Chebyshev, Equal  -  Full Transform  lumped element filter.
Final topology is parallel LC to ground at input, then a parallel LC in series, another parallel LC in series and parallel LC to ground at output.
Shunt elements at input and output are symmetrical.

I actually want the dual of this network.  At the end of the passive template I don't think there is any way to ask for the dual.

I have been trying to figure out how to get to this topology with S/Filter.  I can get close, but I end up with one or more elements
in the middle of the filter that I can't get rid of.

I can take the passive filter output and compute the dual with MathCAD but it is getting tedious.
Can someone walk me through the steps for S/Filter?
