Show blank values in grouping rows

[Anonymous]

Hello All,

I have a requirement where I have to create table report with expand and collapse feature.

I have created a pivot table report, but I am facing an issue while collapsing the group the group row is showing values if all the subordinate values are same, whereas I want to show blank row for group.

Is there any way to achieve this?
