No, I am not saying you are a dummy. I need to send a manuscript to an editor. She would take it as a whole manuscript or as a sketch dummy.
To be treated as a professional, work must look professional. This means it is essential to know what a manuscript should look like.
WritersRumpus.com has a post by Jen Malone, a freelance editor, describing what the manuscript should look like.

Looking at her example it is clear she does not mean for you to do that.
Since I remember she said “page turner” as one of her criteria, I may need to make a sketch dummy.
