How can I use a custom storage class in a Simulink data dictionary?

I have the need for creating a custom storage class which I would like to use in a Simulink data dictionary. I have searched through the documentation and cannot find any reference to this. How can this be done?

Initially, a custom storage class (CSC) package needs to be created as described in the following example:

https://www.mathworks.com/help/ecoder/ug/design-custom-storage-classes-and-memory-sections.html

Once that is done, the CSC can be also used within a data dictionary. 

To add a parameter using the CSC, the "Customize class list" option needs to be selected. This shows all available classes that can be used to add a parameter to the data dictionary:

Now, you can select the corresponding CSC package. In this example, the custom CSC is called myPackage.Parameter. To ensure that the CSC appears in the class list, you need to have the package be visible on the MATLAB path:

Now it is possible to add a myPackage.Parameter and not only Simulink.Parameter. This would be the equivalent of doing "C1 = myPackage.Parameter(1);" in the base workspace, but now we are doing it in the data dictionary:

Now, you can set your desired custom storage class for this parameter. (In this example, a dummy "myCustomClass" was created using cscdesigner just so that it is visible in this instance). See how "Struct" and other storage classes also appear here:
