Place DXF file automatically in map


I am using JOSM and I can import a DXF file to JOSM without any problem with DXF Importer. My question is, would it be possible to automatically place the DXF file in its correct position on the map ? At this point my DXF file doesn’t contain GPS coordinate but I can manage to add any information required to realize this. I know that my question is little vague, should you need any other details or clarifications, please don’t hesitate.

Thank you very much
