Oli C. yeah this is not as simple as it should be. Essentially you should add the new cards to the top and try to follow the same pattern for the position top and margin top/bottom settings. Looks like they go in increments of 4rem. You'll still have to modify every card's margins to make room for them. In my experience, its usually not worth the pain but if you're already committed, I understand why you'd want to push forward with it. I can try providing a video by Tuesday or sooner if that would be helpful, let me know.
