I have had no reason to play with this so forgive me if I lead you down the wrong path.
The import button is at the bottom of the IFC Translator dialogue.
This will allow you to import from any other file - just browse for it (you may need to change the file type to see it).
So no need to export any settings - just set up the original file as you want it.
Then you can import these settings into any other file just by browsing for the original file.
