Configueres supports the use of LATEX in the object description field.
Enter the following LATEX code in the description field: $$\begin{equation} \Re{z} =\frac{n\pi \dfrac{\theta +\psi}{2}}{ \left(\dfrac{\theta +\psi}{2}\right)^2 + \left( \dfrac{1}{2} \log \left\lvert\dfrac{B}{A}\right\rvert\right)^2}. \end{equation}$$
to get:
