mpt.parameter Structure Values Being Variant Dependent

I have an mpt.parameter where value is a struct and data type is a Simulink.Bus.

For example:

tmp = mpt.Parameter;
% myStruct is supposed to be a struct defined before
tmp.Value = myStruct;
% myDT_tstrCalib is supposed to be a Simulink.Bus defined before with elements as many as myStruct
tmp.DataType = 'Bus: myDT_tstrCalib';
tmp.CoderInfo.StorageClass = 'Custom';
tmp.CoderInfo.Alias = 'myAlias_strCalib';
tmp.CoderInfo.CustomStorageClass = 'myCSC';
tmp.CoderInfo.CustomAttributes.MemorySection = 'RAM_CAL';

What I use in simulink blocks is

tmp.x

where x is a field in myStruct.

The upper code produces a structure with names as in myDT_tstrCalib and values as in myStruct when I generate code using embedded coder.

What I seek is using variant subsystems and having some of tmp being in more than one variant with different values.

what shall I do?

You might be able to do this by turning the contents of each variant sub-system into reference model and then setting up each reference model to use instance specific parameters. See this link:

I did somthing like what's in the link but when I generate code, the tmp structure isn't defined as a structure data type; myDT_tstrCalib as it should be. Instead, only the used elements are generated and the name of the structure is something that embedded coder creates on its own.
