I am trying to create a report, that combines 3 different primary modules. I need to be able to gather details from the New Task, New Event, and New Call areas. All are listed under Activities, but do not show up as related modules when I select any of them as the primary module. 

Is there any way to pick multiple primary modules so I can access all the fields needed for my reports? 

Please let me know if you need any additional information from me to help make my question more understandable. 

Thank you for your help!
