Switch-channel-breakout-system-from-Stop-to-StopLimit-orders

20+ year WLD 3.x user ... just purchased WLD 8 and just starting to learn c# and play around with the program. Can anyone help me switch the Stop orders in Cone's channel breakout to StopLimit orders with limit 0.5% more/less than stop price? There are no StopLimit orders yet in the building block section.

CODE:
using WealthLab.Backtest;

        {
         AddParameter("Period", ParameterType.Int32, 50, 5, 100, 1);

        }

        public override void Initialize(BarHistory bars)
        {
         source = new Highest(bars.High,Parameters[0].AsInt);
         PlotIndicator(source,new WLColor(0,0,0));
         source.MassageColors = true;
         pct = 0.01;
         pct = (100.0 + pct) / 100.0;
         multSource = source * pct;
         PlotStopsAndLimits(3);
         source2 = new Lowest(bars.Low,50);
         PlotIndicator(source2,new WLColor(0,0,255));
         source2.MassageColors = true;
         pct2 = 0.01;
         pct2 = (100.0 - pct2) / 100.0;
         multSource2 = source2 * pct2;
         PlotStopsAndLimits(3);

         StartIndex = 50;
        }
