Hi @markratledge
I believe the best way to do it is by using the repeater field as the parent of the other fields. And yes, this is called a nested repeater if you have another repeater field inside it. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/working-with-nested-repeaters/.
Another method would be by using the clone field. But I suggest you use the repeater field if you can because there are some limitations with the clone field.
I hope this helps 🙂
