Packages for court time, not ball machines

We have configured packages to pay for court time. We've found that a if a ball machine is configured to be added to a reservation type with an additional cost, the package will also cover the cost of the ball machine.  

Please consider not allowing packages to pay for additional chargeable items on the reservation. They should be limited to the court time only. The additional items can be paid separately. Really they should have their own package I think.  

I could then sell a package for ball machine usage.  Either way, I just don't want the court time punch to cover the ball machine cost.
