How to create a filter on an Insight report that shows the latest form submission date of each form?

Currently, trying to create a report in Eloqua's Insight that shows provides an overview of the latest submission date of each of our forms. However, I'm not seeing any such options.

As such, I assume we have to create a filter that grabs the latests form submission date and only shows this form submission date. However, I have not been able to set this up.

Do you have any tips/best practices/solutions to achieve such a filter.

Kind regards,
