1. Navigate to the Namspace Custom.View.Item's via the Class Browser
   
2. There are three different ViewItem`s
   1. Create a new instance of a QueryViewItem using the Bulk Editor
      
   2. Assign a query instance of the QueryViewItem to the QUERY attribute either by
      • Drag and drop a query object onto the cell
      • Select the desired Query from the dialog appearing after double-clicking the cell
   3. Create a new instance of a ReferenceViewItem using the Bulk Editor
      
   4. Set the name of the reference property in the REFERENCE cell
   5. Set the REVERSE checkbox if the ReferenceViewItem should be evaluated from right to left instead of left to right
   6. Assign a query instance of the ReferenceViewItem to the REVERSEREFTYPE attribute either by
      • dragging and dropping a metaclass object onto the cell
      • selecting the desired MetaClass from the dialog appearing after double-clicking the cell
   7. Create a new instance of a RelationViewItem using the Bulk Editor
      
   8. Set the REVERSE checkbox if the RelationViewItem should be evaluated from right to left instead of left to right
   9. Assign a query instance of the RelationViewItem to the RELATION attribute either by
      • dragging and dropping a relation object onto the cell
      • selecting the desired Relation from the dialog appearing after double-clicking the cell
