Is there a way to know which nodes in the circuit correspond with which poles/zeros from pz analysis in Cadence?

Cadence calculates a bunch of nodes and shows us the pole and zero frequencies in pz analysis.
Now , is there a way to know which nodes in the circuit correspond with which poles/zeros from pz analysis in Cadence?

I found that there are poles/zeros in my top level circuit that were not there in the individual block.
I am aware input/output impedance play a role here. But I want to make myself well informed.
 

Only in the very simple circuits or in circuits in which the nodes are clearly isolated from each other you can say a single node corresponds to a given pole. In most real circuits nodes interact with each other and poles and zeros reflect that more complex interaction.
