Specifying the string for individual notes

This section in the documentation: https://steinberg.help/dorico/v3/en/dorico/topics/notation_reference/notation_reference_notes_specifying_string_t.html

allows me to specify a string. I don’t see anything different in the score. It kinda seems like a “sul G” (for my note range) indication, but that’s not one of the playing techniques. What does setting a string do in Dorico? And how would I do “sul G” the mostest correctest way?

Setting a string is relevant for harmonics. For “sul G” you’re best off defining a custom playing technique.
