Table Visual - Hide/Show the Totals values for specific column

As we use the table visual and we have different columns with two column which shows information like site and primary key and rest 3 shows aggregated values like within hours, inter hours and below hours.

So an option to hide and show the totals for specific column would be great as currently its necessary to show totals for all columns or not at all.

With that the visualization would be more effective to be produced for customer consider i want to show the total values for inter hours and below hours.So, i would disable the totals for within hours and visualization would be effective.
