Well, that isn't simple without a script.
You can do it with events, but it would take some time, belive me.You would need an event with arrows to select the item, and then variables to each object, then when you press the LEFT or RIGHT arrow, it wuold change the variable value, and in the place that you would click, with the moment variable value that can be changed on the arrows, would appear the right object in the right place.
It would take you like 30 mins to do it without a script.
Well, hope my idea helped you, i can't explain you better that that.
