[NTG-context] Expanding a figure into the second column

I have the following MWE whereby the figure nicely fits the first column. If I now have a picture with more details and want to expand it partially into the second column, it will not work with width=1.5\textwidth , is there a simple way to achieve this? \starttext \startcolumns[n=2] \input{tufte} \placefigure [here] [] {my pic} {\externalfigure [cow] [width=.95\textwidth]} \dorecurse{3}{\input{tufte}} \stopcolumns \stoptext
