On using CopyContentValues, the default status for checked box (except title) is true. But we would like to have false values by default.

At the moment, I (maybe) can override MetadataSetNodeModel.getInitialCheckValue() but it's a little bit violent.

And I would like to change the button configuration by overriding it (PasteMenu is already overrided in my project) to set default checked value to false.
