SSRS matrix subtotal

Anyone know how to format the color of the entire subtotal row on a matrix in ssrs? i can change the color of the group name, but not the aggregate totals in the report columns.

thanks.

you may need to do it as an expression so that it can be done conditionally... good question though, and something I'm going to need to do in the coming weeks.

any thoughts on how that would look?
