Yes there is a way when ever you create a report in query studio gives you three options how to display the data.
1.Data Turn Off-With this option you can see the dummy data that is not queried from the database.
For your requirement you can control the data by create the report in this mode so that report will display the dummy data.
2.Run with all data:Here you can view all the records available in the data base.
3.Run with limited data:With this option we can query the data and view the report with limited data from the data available in the database.
Hope this helps you
