Formatting Agent/Format on dimensions.

Hi,

I have a Balance crosstab in a report. The Balance-Rows are from a dimension. That dimension also has a attributes, which indicate if the Row should be Bold/Underlined. 

I can't find a way to simply format the line bold if the second dimension attribute "Account Schedule Format Bold" is showing 1. And I don't want to format every line statically. 

I tried with the Crosstab styling and "Total, Format Bold" but that didn't work either.

Can't there be a type of Formatting Agent which puts Lines or rows in a defined format (Bold, Underline, Italic, different font) when the second or third dimension is a specific value?
