Create a parameter on a prompt page. Have that determine the value for a render variable that you use to control whether you display the list. Set the prompt parameter's default value such that you will hide the list, and use a value that will display the list when you create the drill through definitions.
Drilling through a report on itself is a very useful thing.
...the only downside is actually developing it.
REMEMBER: You must save the report anytime you want to test it. (i.e. when you run the report from report studio, then drill through (on itself), the drill through version will be the one last saved.
...that minor details has caught me off guard too many times to count.
