The current reports don't have options to select which fields you'd like to include in the report, in what order, etc., although I can imagine that being a nice addition. And I'm not familiar with how WHM** does it, but the reports will be very similar to those in v2.
A separate export for client names/IPs could be created, depending on what data you envision the report containing. Reports are also much easier to create, so you can get in there and write your own without needing to update any core code.
