[NTG-context] Tabulation in itemize list

Dear list, is there a clever way to put a tabulation into an itemize list? I would like to have it on the first line of an item, see MWE. However, when I just insert the tabulation after \item, the table is shifted down. A naive fix using \blank[overlay], on the other hand, places the tabulation too high. Could you help me or indicate a better solution to achieve this? \starttext \startitemize \item %\blank[overlay]\blank[overlay] \starttabulate[|r|p|r|p|] \NC given: \NC $a=1$\\$b=2$ \NC sought: \NC $c$ \NC\NR \stoptabulate \stopitemize \stoptext Thanks a lot and best regards, Florian
