upright lowercase Greek letters in math formulas

Hi, How could I get upright lowercase Greek letters in math formulas (provided that such a symbol exists, of course)? Here's a minimal example: \setupbodyfont[times] \starttext $15{\rm\frac{μm}{μs}}$ 15 μs \stoptext Thank you, Mojca

$\mathgreekupright 15{\rm\frac{μm}{μs}}$ 15 μs I guess you are aware of \setupmathematics[lcgreek=normal] that makes all lower case greek letters upright. /Mikael

I don't want that. I would still like to be able to have italic letters by default, for example for quantities like magnetic permeability. All I need is a switch to make *all* the letters upright, including the Greek ones. So the only question is: is it an oversight or is it on purpose that \rm doesn't also switch the Greek letters to their upright form? Mojca
