Hello Dan
I understand that you are working on a new solution but not shared yet.
Could you share your solution even if I must apply break point and modify few data values.
If you explain me the process, I will be able to reproduce it and solve huge puzzles like this onehttps://www.jigidi.com/solve/x07iovi0/chercher-une-aiguille-dans-une-botte-de-foin/
Thanks in advance
Kind regards
Didier
