When you’re editing a field group there is a little box on the right (if you haven’t removed it) with a link to send a gift.
It wasn’t so much that I didn’t think it was possible, it was more of the amount of code that might be required to get it done. A lot of complicated code would just be difficult to maintain. Luckily, I was able to find a simple, efficient way to do this. I posted the basics of what I did here https://support.advancedcustomfields.com/forums/topic/acf-repeater-sub-fields-are-losing-swapping-content-when-re-ordered/#post-52834. For my plugin it’s a little more specific, limited to only the fields that are removed, so there’s much less chance it will cause performance issues.
