Right click any report showing individual hands and choose Configure Report. Here you can add any stat you like to the report, including the stat "Winning Hand".

Sorry - I thought you said that you could do that filter.
Probably the easiest way to filter for the river being checked through is to add these filters separately:
Hand Details > Win/Loss > Player Lost Hand
Actions and Opportunities > River > Checked River
Actions and Opportunities > River > River Opportunities > Any Raise Opportunity
Select the last filter in the Current/Active Filters page and click 'NOT' Selected at the bottom of the page.
