[NTG-context] Switch number and enumeration text

Dear List, I would like to get something like: 1.1 Theorem instead of Theorem 1.1. Seems simple enough but can't figure out how to switch the number and the text. I have the following MWE: \defineenumeration[theorem][ prefix=chapter, text=Theorem, style=italic, headstyle=bold, headcommand=\groupedcommand{}{.}, ] \starttext \chapter{} \section{} \starttheorem This is a theorem \stoptheorem \stoptext Many thanks, Jethro
