Tony,
I've finally had some time to play with the song Book editor.
Since you must first put any new entries into the main Song Book area and then copy them to your new list, I have come to the conclusion you are better off to make your list by way of the Song Book Editor program.
Just make your main Song Book on the keyboard and then save it and work with making your list in the Editor. You just select New List and name it - from there you can drag and drop to your new list and you can even drag and drop with in the list - this is really very neat stuff. Very fast too.
When you save from the editor, save as a SET.
