[NTG-context] presets for setlayerframed

Hi, Is it possible to set 'presets' for the framed settings of \setlayerframed? For example: \definelayer[text] \definelayer[annotate] \setupbackgrounds[text][background={text,foreground,annotate}] \starttext Testing layers: \setlayerframed[annotate][x=1cm,y=1cm][frame=off, align=middle] {\input ward \par} \setlayerframed[annotate][x=1cm,y=4cm][frame=off, align=middle] {\input tufte \par} \stoptext I don't want to repeat the `frame=off, align=middle` setting everytime (in may actual usecase, these are much more complicated settings). How can I do that? Thanks, Aditya
