How can I programmatically register Data Stores for the Matlab Function block, i.e. without using the Ports and Data manager?

I want to script a Matlab Function (Matlab Function Block in Simulink) for routing model values to global variables, which are linked to memory spaces on a realtime platform after code generation. The routing is defined in an external table, the routing within the model should be generated automatically via script.
The routing with the Matlab Function block works fine, the only step, which I couldn't do programmatically, is registering the global variable / the Data Store to the Matlab Function block. Manually this is done via the Ports and Data Manager.

I had a similar problem and the following solution worked for me (Matalb 2016b). Example Matlab function with the Name 'MyMatlabFcn':
function MyMatalbFcn(u)
global ADwinDATA_1
ADwinDATA_1 = u;
end
Code to add the global data to the Function:
% Code to programmaticaly add a Stateflow.Data Object
s = slroot;
c = s.find('-isa','Stateflow.EMChart','-and','Name','MyMatlabFcn');
data_new = Stateflow.Data(c);
data_new.Name = 'ADwinDATA_1';
data_new.Scope = 'Data Store Memory';
