Oh yes, I got that, sorry.
I was asking if there’s a more succint alternative than nesting the clone group inside another group.
From what I understand there’s none, besides using prefixes, with all the disadvantages you already mentioned.
The best and most flexible way would be to use Flexible content (which is the way I usually go, but in this project I can’t)
Nevertheless, I prefer to get the values as an array using get_field on the outer group, without resorting to nested cycles.
