How can I add room parameters which are used by the IFC exporter?

I added some project information parameter
- IfcProject GUID
- IfcSite GUID
- IfcBuilding GUID

Before starting the IFC Export I convert the GUID values form an external data source to IfcGuid values and set the project information parameter.
It works.
But how can I set the values to a room parameter,
so that the exporter fill the IfcSpace entity property GlobalId?

I have tried some parameter
- IfSpace GUID
- IfcGUID
...
The room paramaters are listed in the category IFC-Parameter with the correct values
but the exporter create another unique value.
#168= IFCSPACE('3vSV7tw5z3TxA$pO1u3ce0',#41,'R025',$,$,#140,#164,'',.ELEMENT.,.INTERNAL.,$);
