Daisy Automotive Engineering Badge Requirements

I don't mind paying for badges as we always have but cant we pay for one book that has all the journeys AND Requirements? In kindergarten (or any level) its not likely that a girl will complete a journey but may want to do the first step of multiple badges before going deeper on another.... Moms / Leaders are being asked to pay for a full badge journey to find out where their girls interest might lie. The girl-led path in lost in this method IMO and leaders have to focus their troop interest which ends up a loss for the girls. Spoken as a Gold award recipient.
