Is it possible to automatically create categories with mapserver?

Question

I have a mapfile connecting to a postgres/postgis database. To create a thematic map I can set a class item and a number of classes, for example:

CLASSITEM  "aantal"
    CLASS
        NAME "0"
        EXPRESSION ([aantal] = 0) 
        STYLE
            COLOR 116 255 117 
            OUTLINECOLOR 178 178 178
        END
    END
    CLASS
        NAME "100-250"
        EXPRESSION ([aantal] >= 1 AND [aantal] <= 2) 
        STYLE
            COLOR 0 255 0 
            OUTLINECOLOR 178 178 178
        END
    END
    CLASS
        NAME "250-500"
        EXPRESSION ([aantal] >= 3 AND [aantal] <= 10) 
        STYLE
            COLOR 0 210 0 
            OUTLINECOLOR 178 178 178
        END
    END

However I have to do this 25 times with different attributes and different values. So I would like to know whether it is possible to do this automatically.

Similar to the option in QGIS where you can set the number of classes and mode.
