The Classic Report allows me to add generated headings. It gives 5 options: Column Names, Column Names (InitCap), Custom Headings, PL/SQL Function Body, None:
I love this powerful feature and I'd like to have the same flexibility for the Interactive Report and Interactive Grid.
Any use case that would apply to a Classic Report would apply here too. Let's say I want to use one report to display the fields and results of a variety of queries. I can do this with a Classic Report but I'd like to be able to do with an IR/IG because these reports have obvious advantages over the Classic Report.
