CollectionControl duplicate item doesn't support any customization of behaviour #1676
Description
This button calls a function that just copies the fields of the object. This isn't always the desired behavior. For instance my objects have a unique ID associated with them, which needs to remain unique. I also have some properties that I want to perform deep copies on during duplication.
An easy solution to this would just be to support the IClonable interface.
Implemented in PR #1677.
