A system and method for cloning objects by configuring a cloned object with properties of a shared object or of a properties collection for a demand event, and for unconfiguring the cloned object for a design event initiated on the cloned object. During a design event, the cloned object may point to or be associated with the shared object or properties collection. A design event performed on the cloned object may actually be performed on the shared object or properties collection with or without user knowledge. Additionally, an embodiment of the invention may allow for dynamic execution of the cloned object at demand time by altering a variable of a property expression.
