Batch Import (how to get the objects from the OBJ file similar to getMAXFileObjectName)

Hello Guys,
Im trying to create a quick script that will allow me to import a OBJ file,  importing is not a problem, but i need to add a suffix  or just select the 1st one of the list or something like that  inside the OBJ file, ( this will be similar to the getMAXFileObjectName when merging a scene) if anyone know the equivalent for importing files, will be really really helpful. Thanks in Advanced.
