Reports using Custom Views

I just learning PHPRunner 6.0.
The menus on program appear to be able to do the following:

1. Create a custom view of a table - I can make this work
   
2. Create a report using a table - I can make this work
   
3. Create a report using a custom view - this does not work. no custom views are listed as available.
   
4. In the "Query Designer" tab of the Report there is a "Add Table" tab, which when I select it has 3 tab's "Table", "View", "System".
   I assumed the tab marked "View" means I can select a custom view to use in the report generation, but it does not list the custom view I created.
   So the question is can "Custom Views" be used as the basis of a Report generation and if so how?
   
   Also, what do the tabs "View" and "System" mean on the table selection part of the report query designer?
   I have looked through the manual and the forum, but can find no reference to this question.
   Thanks in advance for any assistance.
