How to use Simulink.Bus.createMATLABStruct function with Simulink Data Dictionaries

I have a Simulink Constant Block where the value is
Simulink.Bus.createMATLABStruct('myBus');
in order to create a Simple test-harness.
If the bus-object for 'myBus' is in the base-workspace then it works. However, if the bus-object is defined (solely) in a linked data-dictionary then it does not.

you can also try next code:
dd_name=get_param('Model Name','DataDictionary');
scope = Simulink.data.DataDictionary(dd_name);
pStruct=[];
dims=[1,1];
obj='BUS_NAME';
BUS_NAME_MATLABStruct = Simulink.Bus.createMATLABStruct(obj, pStruct, dims, scope);

I also have this issue. Automatically created test harnesses try to set initial condition of ZOH blocks by running Simulink.Bus.createMATLABStruct('.....'); in the mask of the signal spec block. But this fails.

If you have nested buses in your data dictionary it gets even more complicated, because you have to load all referenced buses to the base workspace as well.
Is there an easier way available in the latest releases?
