How do i insert a set of parameters in simulink?

I have parameter sets that serve as input variables for my dynamic simulation in Simulink. There are about 20 parameters in total. That is why I do not want to import them individually into Simulink. The aim of the simulation is to analyze and display the effects of changed data/parameters.

Each changed parameter set should be an object of a class and organized in a Matlab initialization file.

My approach:

I save all parameters in a structural array. I load these into the workspace. In Simulink, these parameters should then be further processed with a Matlab function. I define my struct as parameter data as the type. The error message "Invalid setting for parameter "Datatype" appears.

Does my approach make sense? Or is there a different way?
