How can I edit photospheres in Ps Elements 18?

Hello Community,

I wondering if there is a way to view and edit photospheres in Ps Elements 18? (images captured by a Ricoh Theta, LG Gear spherical camera, or similar). The only import and projection options I can seem to get is equirectangular. I want to be able to edit in full 360 view.

Is there a hidden control that I'm missing? Or does anyone know of a work-around?

Thank you!
