If you just want to create an assignment placeholder with a title and a date, you can create an assignment shell in an assignment group.
Assignment groups [1] house the different types of assignments you may want to keep in your course, such as assignments, discussions, quizzes, surveys, etc. If you create assignment groups in your course, students can filter their assignments page by assignment type to view the same groups. Learn how to add an assignment group.
To create an assignment shell, locate an assignment group and click the Add Assignment button [2]. Assignment shells only include fields for the assignment type, name, due date (optional), and points. You can add assignment details at any time by editing the assignment.
