How to set substitute value for variable?

How to set substitute value for variable?

Hello!
Is there a mechanism for programmable set substitute value for some variable like it done with Replace (Off) and Replace (ON) Actions?
Detailed description:
1. We have a variable QS.Position linked with IEC870 - IEC 60870-5-101-104 driver and used T31 type of frame.
2. We successfully set Substitution Mode with C# code like:
zenOn.IVariable var = this.Variables().Item("QS.Position");
var.StatusString = "NET_SEL=1";
var.StatusString = "ALT_VAL=1";
in other words, we set same status bits as Replace(ON, Off) Actions do.
3. We can't change of QS.Position in substition mode with SetValueWithStatus method, that in case of changing another variable linked with Internal driver value works fine.
