Importing IFC4

Hi is there a way to import IFC4 to UE?
I’m new to UE and have a file in the gauß krüger coordinate system and want to use map conversion to import the file into UE so that it is correct georeferenced but the unreal plug in only supports ifc 2x3. I need this because I use the Cesium plugin and this uses the WGS coordinate system and when I import the IFC file it floats somewhere in nowhere.
would be super cool if someone could help
