Let us group estimate lines (or packages) into an option group where the customer can pick only one, like Good / Better / Best programs. Today customers can check more than one, and the only way to steer them is the "Recommended" flag. For multi-visit rate-matrix lines, it would also help to show the customer the price per visit and the number of visits along with the total, for example "$108 per application × 6 = $648 for the season." Many lawn care programs are quoted per application, so customers want to see both.
