For IfcMaterialLayerSetUsages, is it possible to realize a negative DirectionSense?

Would be nice to have this for IfcSlabs, that is, if the origin is at the top of slab, setting the floor elevation is a lot easier by just setting the Blender's Z value.

    Something I have also been tweaking in the 'IfcMaterialLayerSetUsage' for IfcSlab but I don't get any results and for some time now I thought I was missing something with the AXIS direction or not doing it right. Now I know am not alone ?.
