[NTG-context] Page with subsection following a subsection

I would like to have a subsection start on a new page. This can be done with: \setuphead[subsection][before={\page}] But when I have had a section before the subsection instead of a subsection before the subsection, I do not want a new page. (Subsections I want to have divided, but the combo section/subsection not.) Is this possible? -- Cecil Westerhof
