You can create your own report by going to Settings > Report Templates in the Investigative Reports section. 

Click on the "add report template" button. 

Label the report, choose which case types you want the report avail for and insert your header/footer. 

The header/footer needs to be a single page word doc with no content except the header/footer. 

You can use the "variables" to have certain information automatically inserted into the report.
