Is it possible to make correct smoothing in Poser without rebuilding the geometry?

Simple example. Common situation, 2 segments bevel:

Tried anything, but cant import it in Poser with correct normals

It can be fixed with adding more loops around flat surfaces, but too many models in internet have same 2 segments bevel, and many of them are too complex even to add some loop cuts, so would be better to have other ways
