How to create a Zoho CRM report with 2 child modules

Hi all, 

Is it possible to create a Zoho CRM report or chart with 2 child modules? After I add the first child module, the + button only adds another parent module. It won't let me add multiple child modules at once. 

We don't have Zoho Analytics and would like to see if we can do this in CRM reports. 

Thank you, 
Jules
