Linking multiple meshes/breps to one Ifc Element

unhandled

#1

Hi!

The IFC specification allows for elements that consist of multiple representation items. For example Revit ifc export of windows uses it to assign a different material to the sash and the glass parts of the window. it seems that IfcShapeRepresentations just has to point to multiple Representation Items, like this:

IFCSHAPEREPRESENTATION(#102,'Body','SweptSolid',(#218,#244,#270,#296));

Is there a way to create elements like this in GeometryGym? I tried to connect multiple Representation Items to the Ifc Element in GH but this only creates a separate element for each Representation Item.
