Using referenced model arguments in non-tunable parameter fields.

Hi, guys

I want to build a model used as referenced model in other Simulink models. Then, I encountered errors about using referenced model arguments in non-tunable parameter fields. This error is clearly stated in the Simulink documentation as below.

Simulink generates an error if you use a model argument in an expression that is nontunable because of Tunable Expression Limitations.

This restriction is pretty strict IMHO. I have several parameters that really need to use the model arguments to pass data values in.

Is there any way to work around this problem?

Thanks in advance!
