Knocked this up today after failing to find a suitable example.
Left-click and drag to highlight the objects you want to copy (you will need to make sure that you're selection starts on top of an object), press Control & C and then left-click to paste the copied objects. Works for multiple objects as long as they're allocated to the qualifier '0'.
The only thing you would need to change is the create event for any additional objects you add to the qualified group. I've commented where you would need to do this.
Extensions needed:-
ForEach object
Easy Grid object
Active System Box object
Any questions or if you've managed to simplify my events, please post here
