When changing trap name, give the option to change the supplementary trap name also

[bevan]

When you want to change the name of the trap, it would be good if it would ask the user if it would also like to change the supplementary trap to the same name.

I have to say that I have mismatched supplementary trap names because I forgot to update them at the same time as the main traps when I renumbered the line. This feature would have been helpful at that time.
