[NTG-context] Reference to a subitem

[Diego Depaoli]

Hi all,
referencing a subitem I get also the item (1.a, 2.c and so on).
Can I split them or get only the subitem?

\starttext
\startitemize [n]
\item [number] one
\startitemize  [a]
\item [letter] letter
\stopitemize
\stopitemize
Look at number \in[number] letter \in[letter]
\stoptext

Normal output:
Look at number 1 letter 1.a

Wanted result
Look at number 1 letter a

Many thanks
