Have "Each Player based on Membership" not apply to ball machines

We charge courts fees based on membership. The "Reservation Fee Responsibility" option of "Each Player based on Membership" works very well for us.  We can have a 4 players on a reservation and collect 4 different amounts from each of them.  It's perfect.

Where this falls apart is when we add a ball machine with a fee to a reservation.  What happens is each of those players have to pay the ball machine fee based on their membership. It doesn't make sense to charge each player the full fee for the ball machine. Either leave the ball machine fee responsibility with the reservation owner or allow it to split equally between (not multiplied by) the players on the court.
