# Principal square root of Pauli Y gate in Qiskit?

I've seen a similar question asked (How do I compute the square root of the $Y$ gate?) but I'm trying to understand how I can use the gates $$Y^{\frac{1}{2}}$$ or $$Y^{\frac{1}{4}}$$ in Qiskit in terms of other building blocks, if it is possible.

Is there a way to use the gate $$Y^{\frac{1}{2}} = \begin{bmatrix} \frac{1}{2} + \frac{1}{2}i & -\frac{1}{2} - \frac{1}{2}i\\ \frac{1}{2} + \frac{1}{2}i & \frac{1}{2} + \frac{1}{2}i \end{bmatrix}$$ in Qiskit? I can say that $$Y = iRY(\pi)$$ and compute the square root manually, but how can I describe such an operation, if possible, in Qiskit?

circ.append(YGate().power(1/2), [qbit])

Where circ is the QuantumCircuit object and qbit is the register to apply the gate on.
