SWR - array of data in one request, one item from array in another

So I am using SWR in my nextJS app and I have two routes GET /courses gets all classes you are enrolled in (of type CourseData[]) GET /courses/:course_id gets specific details for one course (of type CourseData) SWR does not know the relationship between these, so it refetches even tho we have the data from the all courses page. Does anyone know of a way to just use the data right away without requiring another fetch?
