Hey Linda! I would be happy to help you. You can do it either way you said! Once you get it into the script you can copy and paste/drag and drop. Keep in mind you can save it to the cues library with the "star" button as well so you can insert it from there next time and it's ready to go with all formatting, background, etc.
But if you want to go ahead and get things in order even before that stage of inserting it into the script, you can do so in the library just like you said. It's really easy to do if you put it in the "list" mode (a button on the top right with little lines) instead of the big page mode, and then you can just use that little stanza drop down and add button to add as many instances as you need of any stanza, and drag them into order. Then it will be that way when you insert.
