Crosstab - bold headers

Hello all,

I have crosstab like this

                    date     date .....

sameText      data     data

sameText      data     data

sameText      data     data

sameText      data     data

sameText      data     data

and same rows must be bold, I tried use highlight manager but rows are too many I would like to ask is there any way how to do this dynamically ?

Any ideas will be helpfull.
