Genereating a2l using Custom Storage Classes

My question is about how to generate an asap2-File (.a2l) with the Embedded Coder. I'm using custom storage classes for tunable parameters in the model. Parameters are defined as data objects, the appropriate class is derived from Simulink.Parameter, but uses a custom storage class. This way my parameters unfortunately do not appear in the a2l-file. If I set the StorageClass to ExportedGlobal, they will appear. But I have to use the custom storage class. What can I do that the parameters will appear as characteristics in the a2l when setting the storage class to custom??

Thanks for advice...
