Don't send empty reports

Hi

We are using an FAZ1000D with FortiOS 5.2.3.

We would like to send out a threat report every morning, but only if threats have been detected. Is this possible? We don't want to receive any empty reports.

Additionally we would like to hide pages in a report.

The default threat report has 3 categories (Malware, Botnet and Intrusions) would it be possible to hide the categories in a report which don't contain data?

Thanks & Brgds

Sander
