Howdy @susan_rothbard ,
Hope that you are doing well. Thanks for sharing your question. Also, welcome to the community!
Currently, announcements are ordered in the order than they were created OR by display/publish date.
How do I delay posting an announcement until a specific date in a course?
From a previous discussion on this same question, a suggestion was provided where some instructors keep their announcements in a sandbox and only import them into a class as they need them.

Hope this has been helpful to you,
