preserving 3ds max Group pivots?

Hi, doing an archviz project and I wanted to be able to open windows easily so I grouped the window panel and the glass in 3ds max and set a pivot for the group object where the hinge would be, but when I import, the group pivot is centered on the window.

am I doing something wrong?

Probably something we haven’t considered yet. Group in max are simply dummies and we probably never looked at customization of their pivot, like we did for meshes.
