\setupsynonyms[nomenclature] [criterium=all,location=serried]
here I use location=serried, becasue I found the synonym is not in the same line ( higher than) the meaning.
But I want a three-column nomenclature list. The first column is the synonym, the second is the meaning, the third is the si-unit of it, if the synonym has an unit. Like
------
p Pressure of xxx Pa
l Length of xxx m

How to redefine the nomenclature command?
