Hi April,
What you may want to do in this case is create a Multi Record section instead of a Single Record section.
When you generate your code for the page this content of the day goes on, choose to only show one record. If you have the sorting set to "date DESC" then it will only show the latest post made.
Then create a separate archive section on your website, but now choose to show all records.
Make sense?
Let me know if you have questions.
Kenny
