Hi Nimish,
As the dates are in separate groups, there isn't an easy way to do this.
I have something in mind, however, could you tell us where would you like to display the percentage?
If you display the percentage on the same rows that displays the date, then it would repeat needlessly.
Are you OK with the percentage displaying on the footer with each date value showing up against it - Much like a summarized view?
