model reference variants control using block mask parameter

Dear all,

is there a way to implement model reference variants where the variant selection is controlled by a mask parameter rather than using parameter that is defined in the base workspace. I'd like to define a parameter structure in the workspace but passed to the model reference block in a mask and use values from that structure to drive which model variant is chosen.

Example Two models are defined to represent a physical phenomena, i.e. an idealized and a detailed one. In the base workspace a parameter structure is defined as follows:

paramStruct.physModel_A.isIdealized = true;  % presumes that model is idealized
paramStruct.physModel_B.isIdealized = false:  % presumes that model is detailed

The goal is to use the element of the parameter structure to control the variant selection of the model reference. So far, model reference variants works if the condition for the variant selection is explicitly defined as parameter (and not as a part of a structure) in the base workspace (e.g. isIdealized = true).

Many thanks in advance.

I hope this helps.

Thank you,
