nomenclature format

[Wolfgang Engelmann]

The output of my nomenclature list is

symbol
                 description-text
                 description-text
                 description-text
                 description-tex

I would like to have it

symbol
description-text
description-text
description-text
description-text

since I use twocolumn (koma script book)
and a long symbol takes away too much space for the description text

I can't find a way to do it under lyx

Doe somebody know?
