Answer:
You can add an existing rubric when creating or editing a grade item.
Go to Course Details → Grading Schema, click New Course Grade or edit an existing one, and check With Rubric.
Then select from available rubrics — including those created in the course (Details → Rubrics) or saved system-wide under Home → Rubrics.
If you don’t see the With Rubric option, it means the selected Grade Link Type does not support rubrics.
