Ok but hm.. The thing I'm trying to do is, (it's an interior decorating game) create a bunch of sprites here and there. And then you can select one sprite (you click on it and a small menu appears). Then you can rotate it and so on, and also delete it.
So if the user has created multiple instances of a table for example, I only want the selected table to be destroyed and not all instances.
When I tried to put all furniture sprites in a family and add a variable to the family, then it destroys all the furniture :/
Here is an test version so you can see
