Unofficial DMX in Unreal MegaThread. 4.26+

Good evening I read that as regards the import of the GDTF format, only the XML data are imported without the model I wanted to know it is possible to insert an fbx or 3ds model in the window that appears when you click on the XML file and create the fixture using give you XML with the imported 3d model? If it can be done how can I get this result?
Thanks!!
