\setuphead[chapter][align={nothyphenated,notcollapsed}]

Would that mean there's no way to collapse the hyphenation throughout the entire document from a single location? That is:

\nohyphencollapsing

\setuphead[section][align={nothyphenated,notcollapsed}]

\setuphead[subsection][align={nothyphenated,notcollapsed}]

\setuphead[subsubsection][align={nothyphenated,notcollapsed}]

Would "\nohyphencollapsing[head=yes]" allow the setting to apply once to all areas?
