Return outputs with zero counts

I am running a simple 3 qubit circuit which produces the following results:

{'000': 5, '001': 3, '010': 10, '100': 5, '101': 7, '110': 7, '111': 4}


There are no counts of 011. Is there a simple way within qiskit to also return the result '011': 0? So the final results would be

{'000': 5, '001': 3, '010': 10,'011': 0, '100': 5, '101': 7, '110': 7, '111': 4}


Currently when I run this circuit I get an error as I am trying to call res['011'], where res is the list of results. I cannot just increase the number of shots unfortunately I am constrained to this number of qubits.

res.get('011', 0)
