Download: Multi_Importer
(Last Updated 10/04/2012 for Softimage 2011, 2012)

This plug-in adds an item to the File>Import menu to let you import multiple files at once. Navigate to a directory containing EMDL, OBJ, FBX, or LWO files and the plug-in will let you import any you wish. Multi-selection is enabled, and you can import multiple file types at once too.

Options pertaining to LWO and FBX are currently limited to scaling only since I needed this tool to deal primarily with multiple OBJs. More detailed options may be added later.
