No need for a program Sporty. Just use the same lens material with the same Rx and same decentration/seg hight for the balance lens. If the prescribed lens has cyl, leave your balance lens axis the same if it's at 90 or 180. Any other axis, add or subtract 90 from it to get a perfectly balanced, balance lens.
