[NTG-context] Verbatim Textbox with Reference NUmbering

This is a longshot, but would be great to have. Below I have at MWE1 the
verbatim codefragment textbox I am using. I found in the forum MWE2 which
is a textbox with an automatic reference number. Is there a way to get the
same for MWE1 with automatic reference numbering like 1.1, 1.2 etc for
chapter 1, codefragment 1, 2 etc. with the possibility that in the text I
can refer to the codefragment like \in{codefragment\space}[code:ccpsample]
similar as to tables and figures? Thanks Jeroen
