How to display each group at the top of the page in CR

Hi,I have Groups to be displayed - Down then Across in WPF CR project.

I could achieve grouping successfully.

I want each group to start from the top of the page.

The group header shown in Red boxes to be at the start of the page where the Green boxes are placed.

Group should not start from the space left over by the first group's details.

Any unused space by the earlier group should remain blank.

Is this possible in Crystal Report (Version - 13.0.15 - VS2013 - 32bit )

Please guide me how to do this.

Thanks.
