I have a question regarding modifying Qiskit circuits. I have a set of circuits that are pretty similar to each other. The only difference being some gates in the beginning of each circuit. I was wondering if instead of creating new circuits each time, I could just append gates to the beginning of the circuit. However, currently, all the methods I am aware of that act on the QuantumCircuit only append to the end of the circuit.
Is there a way I can add certain gates to the beginning of a Qiskit Circuit as opposed to creating new ones each time?
