Free Member Hours to not include Ball Machine bookings

We are not able to set up our Ball Machine as "Equipment" because any membership level with "free hours" would be able to use these free hours towards the ball machine.  As a work around, we had to set the ball machine up as an instructor. 

The functionality for booking equipment is obviously better and preferred, but apparently there's no way currently that we can restrict a membership level from using whatever free hours might be included per week or month with their membership level from being applicable to using the ball machine if we set it up as it was intended to be set up.
