Possible to have multiple results sets in new Workbook mode?

I am building a query using the editor in the first step of a TDP workbook flow. When I run the query, the results are displayed in the Result Sets tab as expected, but each subsequent run of the query does not generate an additional Result Sets tab, it just replaces the previous one. Is there a way to have multiple result sets like in a normal query editor session?

This is an option we set to one. It was intended for users to be able to change it, but looks like it got hard coded. I entered QAT-14703 to make if configurable
