Help regarding requirement 1.2.7 (NSC reviews)

I'm relatively new to PCI DSS compliance and wanted some help with requirement 1.2.7. At the moment we are doing a manual review in the sense that we are taking screenshots of all the control rules for our reports.

I wanted to know if there is a better way to go about it than this. We are using Fortigate firewalls at the moment so and the only way to export rules we've found is to get them into a CSV file.
