btCompoundShape with SIO2

Is there a "supported" workflow for creating compound objects? SIO2 doesn't seem to support those at all. I tought of creating them manually but what do I have to take into consideration? I probably have to render the objects myself and can't even use the original SIO2Objects or has anyone else experienced with this?

Thanks,

After loading from .sio2, simply get back the handle of the object, after that its up to you to initialize the _SIO2object->_btRigidBody, if you need vertices for you shape simply use sio2MapBuffer to get access to the vertices and write your own routine to assign the necessary data to your shape.
