Do you recommend placing signs indicating the direction of the qiblah in the women's prayer area?

The Shaykh : Many women, when they go up to the upper mosque, look down into the men's mosque to verify the direction of the qiblah. Because of the reflective glass, they assume the glass is behind them, when it is actually in front of them. Do you recommend placing signs indicating the direction of the qiblah? May Allah preserve you.
There is a difficulty here. Does anyone know? We will look into it, if Allah wills. We will look into the matter.
