Format Totals column in VizLib Finance

Hi,  I would like to start using the VizLib finance table more for simple prescriptive table taking advantage of the group functionality as a layout feature the business love.  One feature that is lacking though is the ability to format the total row - meaning that it just blends into another row, you cannot even make it bold.  I have completed a work round by creating the dimensions as a dual and applying the logic of "non template" from within the script but this is a real pain.

 Would it be possible to add in the ability to link the total total to the styling options to allow it to be customized within the chart?  This would greatly increase the use cases for the finance chart within our business

Thanks
Paul
