Hi @etiennedupuis
Have you seen that in later versions of ACF you can collapse/shrink a repeater row to a single “line” with your chosen field value on it?
If you still find it unmanageable, to be frank, you should reconsider how you structure your data. There are more and worse issues with dumping everything into a repeater field. For example hitting your servers limits like max_input_vars resulting in you unable to add information.
