How to display materials double-sided in Viewport?

V-Ray V-Ray for 3ds Max General

Hello,

I was wondering, why in the Max viewport I can’t see materials doublesided.
2-sided material is turned on, it renders properly in VFB, but in viewport I see them only single sided …which makes hard to work on them.

Thanks
