[NTG-context] Default length units - can I change them from pt to bp or dd?

Can I [easily] change the output of commands like \showlayout to show dimensions in bp/dd rather than pt? As a traditionalist I try to stick to dd/cc standard. For compatibility with others I sometimes have to use bp standard. I find TeX native standard of pt useless and very confusing. I would be happy to never see those pts around any more. Is that possible with ConTeXt? -- Andrzej Orłowski-Skoczyk
