Code-changes-to-optimizable-parameters-are-not-reflected-in-the-GUI

I have a C# coded strategy which defines a couple of optimizable parameters:

CODE:
   //                                                def, min, max, step
         AddParameter("NumLevelsHigher",   ParameterType.Int32, 5, 0, 20, 1);    // 0
         AddParameter("NumLevelsLower",    ParameterType.Int32, 10,  0, 20, 1); // 1
         AddParameter("DistancePct",   ParameterType.Double, 0.5,  0.1, 5.5, 0.1); // 2
         AddParameter("StopLoss1Pct",    ParameterType.Double, 0.0, 0.0, 20.0, 1.0); // 3
         AddParameter("StopLossLevel", ParameterType.Double, 0.1, 0.0, 20.0, 0.25); // 4
         AddParameter("Timeout",       ParameterType.Int32, 15, 1, 100, 1); // 5
         AddParameter("GateClosureTime", ParameterType.Int32, 59, 56, 62, 1); // 6

When I open such a strategy in WL8 I get a nice GUI for these parameters:

Now I tend to adjust the parameter definitions in code from time to time.
These changes are not reflected in the GUI instead a new backtest runs with the (old) settings from the GUI.
This is quite disturbing.

On the other hand, in optimization, the Optimization Parameters always precisely reflect my current definitions in code:


So my #FeatureRequest:
Make the settings in the parameter GUI for simple backtests reflect changes in code.
If I change a default parameter value in coide, I want to
1.) see this default value in the parameter GUI
2.) make the backtest use this default parameter value
