Add item from one board as sub-item to another board

Hi everyone! I am looking for a solution to the following problem: I have one board for courses (item = course) and one board for students (item = student). There is a one-to-many relationship, meaning one course can consist of multiple students. I would like to create an automation to add students as sub-items to a course item. I have looked around and I am not sure how/whether this would be possible?

Hey Cristiana, we’re developing this feature on Same Item Multiple Boards - we expect to ship it very soon!
