Hierarchie Header formatted bold

I have  a simple cross table within DS 1.5 presenting a Hierarchie node and the Level below.

I want to format the Hierarchie node row - the "total" -  in bold letters - like a total row usually would be.

Is there a easy way to do this?

At the Moment it is plain as the rest of the cr-table.

I know ERs to  do more easy formatting are already accepted...

But I would need easy formatting right now ;-)
