Customizing Reports through SoapUI

Hi,

I am new to the reporting concepts used in SoapUI. So needed some help in customizing the reports.
I went through the support topics mentioned on the website but couldn't figure out how to modify the particular subreports.

I generated subreport 'MetricsReport'. Here I can see that there are 3 sections - Overview, TestCase Summary, Base Metrics.

Now I wanted to skip the 'Test Case Summary' section & just have the other two in my report. I checked the main & the sub-report but the only thing that I could see was that this was probably governed by the field 'category' which was mentioned like $F{category}.

If I understand this correct & that this is an in-built field parameter used by SoapUI, could I modify it. And if not, is there any workaround for the same.

Thanks,
