We don't provide a direct way to do what you want, but ERXEOAccessUtilities._rawRowsForSQLExpression is close. You should be able to take that code and down inside of the loop, you could probably manually add snapshots to EODatabase and then trigger faults for them one-by-one. When you're done with each row, you can explicitly forget the objects you faulted and the snapshots should get refcounted to zero and go away. It might be useful to add a method that does this.
