Female area leaders?

Does anyone know whether the church has ever considered calling female leaders (either full presidencies or a single rep for RS, YW, and Primary) at the area level?

We have area seventies and area presidencies. And we have boards for each auxiliary. But I have to think the general primary presidency is traveling constantly which is a huge burden. And they can’t cover everyone. And having area level female leaders could provide better trainings to stake leaders and could provide a pipeline for general leadership.

Anything wrong with this idea? Have them called the same way as area 70’s?
