Excluding records from pivot table report in Eloqua Insight

Good morning,

I have a question about excluding records from the pivot table report. How can I exclude specific rows that I do not want them to be there?

This is the layout of my report:

I would like to remove whole rows of form submission data including first name, last name, VAT number, phone number, street etc. Records do not have anything specific in common, so excluding them by filter "not equal to" unfortunately does not work. Is there any option to exclude whole row of data? I think there is such option for a normal table (not a pivot table) in Insight.
