How to add Spawnpoint Changes/Checkpoints 2D Platformer(C#)

How can I add Spawnpoint Changes at each level of My game which is a 2D platformer with 11 levels. I need a checkpoint at the beginning of Each Level that sets the Spawnpoint to there. I do not know how to code so the easier the better or if there is a way to do it with no code at all.
