[NTG-context] Adjusting parameters for a single page

Hi everyone, I know it is possible to make local changes by enclosing text in \start \stop pairs to make local changes. Then, there are also commands that only affect the next/current paragraph, such as \looseness. But is there a similar mechanism for page-layout changes? For example your penalty settings allow widows and orphans, but on one particular page you want to change the penalties. Or, you use \setupalign[height], but on one page you want to use \setupalign[bottom] instead. Is there a way to do this ? Best, Denis
