I am currently working with the EstimatorQNN from Qiskit to construct a Quantum Neural Network using a custom Parametrized Quantum Circuit. But I want to change the observables in the EstimatorQNN.

By default, the observable returns the product of Pauli Z operators across all qubits in the parametrized quantum circuit. However, I am interested in having the observable return the Pauli Z operator for each qubit individually.

Could you provide guidance on how to modify the observable parameter to achieve this specific behavior?
