Composition attributes: Create from copy
If a composition reference is displayed as a table in a form, you can create new objects inline there. You would also like to create new objects from a copy of an existing object - if many similar objects are to be created.
You could select a line and use the "Duplicate" button to create a new line containing a deep copy of the selected line.
