[NTG-context] Referencing line numbers inside a typing

Hi list, is there a (preferably easy) way to reference line numbers inside a typing? Minimal (not working) example: \setuptyping[numbering=line] \starttext In the following typing, \in{line}{}[line:intyping] is really interesting. \starttyping This line is so interesting. \stoptyping \stoptext Thanks, Stefan
