I can use this code to display page 5 from a PDF:
I am making a teacher's guide for a workbook (workbook.pdf). I need to be able to display on the page all pages of a particular section.

The teacher's guide uses the same section titles as the workbook, e.g.:

17-A: Title
17-B: Title

In other words, there is 1:1 pairing of section titles in the teacher's guide and the workbook.

Is there any way to tell ConTeXt to display all of the pages for a particular section?
