Question: Modify the storage class in the data dictionary programmatically

I have my data dictionary build and running for my model. But all of my signals are set automatically to sotrage class to ExportedGlobal. Does anyone know how to change the StorageClass to Auto programmatically?

Editing a storage class is editing the properties of a Simulink Signa Object.
 
To do this, edit the Simulink Signal Object programmatically, not in the Model Explorer.
 
The method is described in the documentation.
 
% ex
% Define signa object 
mySignal1 = Simulink.Signal;

% edit storage class
mySignal1.CoderInfo.StorageClass = 'ExportedGlobal';
