3ds max plugin Y axis Up Right Handed coordinates

We are using physx 3d max plugin (3ds Max DCC plug-in 2.8.9 (v03131509)) and export physx scene for 3.x engine as xml file.
The problem is, we couldn’t find an option to change up axis and I strongly believe there is none :(
In order to fix the problem we rotate and translate relevant objects. But this trick doesn’t seem to be a good solution more over I suspect it will work for constrains. (And it is problematic, we are doing a lot of tricky things to export the scene properly)

Probably there are people like us out there. How did you overcome the problem ? Thanks

It is a pity. The plugin does not support it now. We will consider it in future. Thanks for your advise!
