We need this too. We sell lawn care as Good / Better / Best programs. Good is a 6-step fertilizer program, Better adds weed control and aeration, and Best adds bed, pest and mosquito services. Right now each package expands into separate lines, so offering all three puts more than 25 lines on one estimate and customers can't tell which lines go with which program. We'd like each package to show as one line with the package name and a combined price, priced from each service's rate matrix, while keeping the individual services behind the scenes for scheduling and billing.
