[NTG-context] Another question about definerefereformat

Here is another question, I was wondering about. What is the ConTeXt’s way to provide the “right” (or “left”) argument when \definereferenceformat[text=…] is set? Starting from this example: \starttext \definereferenceformat[infig][text={Figure }] \startplacefigure[reference=fig:A] Some figure. \stopplacefigure This is \infig[fig:A]. \stoptext I would like to output “This is Figure 1 a.” Obviously I can type “This is \infig[fig:A]\,a.” to get the desired result; however it does not seem very “ConTeXt-ish” to me as “This is \in{Figure}{a}[fig:A].” is much more concise. Is there the possibility to have something like \infig[right=a][fig:A]? Thanks again. Benjamin
