Impassable Setting Reset

I have Object A which has a Physics behaviour, and the Impassable setting is set to "Yes". Every time I create a copy in the editor (by draggin from the object palette Object A into the layout), this setting resets, putting the just made copy of Object A with the Impassable setting "No".

Is there any way to solve this?

When you drag an instance in from the object pallet it creates a new instance with default settings. If you want to duplicate an instance already in the layout, click and drag that object while holding Ctrl, and it will also duplicate its settings.
