You could do that automagically. You can open the Lectora.awt in any xml-editor and copy paste any elements you need. Biggest problem would be that you need to figure out how the elements in the xml/awt interact with eachother.
If you need this once. Use Tim’s advice, for sure the easiest approach.
If you need this more often. Send me a sample setup and i can create a script for you that will create a Lectora.awt with the needed amount of elements.
