Help in CSS

Hello got a pivot table with one dimension (columns) and several expressions
I managed to make the labels and the values of some expressions to be bold as they represent the total of other expressions:

I managed to accomplish this using the multi-kpi by adding the below  css "code":
tr[tid="data.row"]:nth-child(8) div {
font-weight: bold !important;
}

with this I managed to bold the third row "Internal" and so on
now I made a copy of the above pivot table but I added other row-dimensions and I wanted to keep the same styles; so what I noticed is that the multip-kpis had effect on the new pivot table but they worked well for the first set of expressions as per below:

so my question is how to make the bold consistent as per the first pivot table?
