As with loading multiple figures, or mutiple props, where poser also renames them for you, the best trick is to rename them yourself, before Poser does.

if you know you are going to import multiple magnets, rename them immediately after import to a name that makes sence to you.
As said, all 3, the magnet, the fall-off zone, and the base.
