Unfortunately Power BI doesn't support such formatting options yet. As an alternative, you can apply conditional formatting as background color for each column ( Sales, Product and Sales% ) to highlight as totals.

You may also explore possiblities in the custom visual Inforiver for 360-degree analytics with data writeback which is ideal for this sort presentation.
