voltage controlled model selection in Keysight ADS

Hi

I have to use two distinct models depending upon the node voltage, something as follows:

The diodes D₁ and D₂ have different properties/models. If the voltage at node v₁>0, then I want node v₁ to be connected (perfectly shorted) to the D₁ (as if D₂ is not there at all), otherwise to D₂ (as if D₁ is not there at all).

I wonder if this kind of voltage dependednt use of model would be possible in Keysight the ADS? In fact, I have tried it using SDD as shown in the following:

But, I am not sure if SDD results into a perefctly shorted connection. I guess, it "shields" the parasitics of diodes from rest of the circuit.

(1) If my way of using SDD in this scenerio corect?

(2) If not, what else could be a better solution?

Thanks in advance.
