Insert Suppressed Member Functionality Question

You are talking about inserting suppressed members; however, your screenshots are about drill down. There are three options for insert suppressed. You can allow the user to insert all dimensions on rows, do a nested (this will let the user pick members from 2,3,4 row dimensions) or do innermost (this will be the last dimension).

The one thing to keep in mind is there needs to be at least a single row of data to make it work.
