[NTG-context] descriptions -- symbol between head and text

Hi, is there a way to get some text between the head and the text of a description. Enumerations have stoppers, but I couldn't find an equivalent setting for descriptions: The output should look roughly like this: ABC: asdfasdfasdf jklöjklööjklö CDE: asdfasdfasdf jklöjklöjklöö Denis %%%%%%%%%%%%%%%%%%%%%%%%% \definedescription[deflist][ headstyle=normal, style=normal, alternative=hanging, width=fit, margin=1cm, distance=0em, ] \starttext \startdeflist{ABC} \input knuth \stopdeflist \startdeflist{CDE} \input knuth \stopdeflist \stoptext %%%%%%%%%%%%%%%%%%%%%%%%%
