[NTG-context] registers: how can I place a command around the whole of the page numbers of an index term?

Hello list, i'd like moving the page numbers in my index to the right, with a \wordright. \setupregister[index][n=1,alternative=A] \starttext \CONTEXT\index{\ConTeXt} \page \LATEX\index{\LaTeX} \page \CONTEXT\index{\ConTeXt} \page \placeindex \stoptext The index is at page 4. I want to move the numbers "1,3" and "2" to the right. The parameter pagecommand is for the single page number, i want to put a command (\wordright) around the whole block of page numbers. How can i do that? Greetings, Massi
