So what would be good for you, would you like it so when you click the objects status screen where it says Unnamed, that it would open up the dialog as normal where you would name it, but instead of empty name it puts in something like "Cube-01" or "Sphere-01" or "Solid-01" etc etc. That would make it so a quick click on OK creates the name, or you simply have to start typing so you give it the name you want.

If C4D supports Step file format that handles the MoI styles and object names better than OBJ
