I know ConTeXt TOC is quite customizable. However, I don't figure out how
to include a page range next to section labels. For instance, something
like that:

1. Chapter  . . . 1 - 4
 1.1 Section . . . 1 - 3
 1.2 Section . . . 3 - 4
2. Chapter . . . 4 - 7

I've seen a LaTeX implementation here:

Is something similar (or maybe better) possible? Thanks in advance.
