two Subviews (not nested) in data tables

cuwebix

I have a json data which i am trying to present in UI. I can only add one object to the subview. In below sample.
I have a ChangeObject(objid,name)-->coverpage/affectedItems
I am able to display the Change and coverpage, how should i show the affected items of coverage?
