How can I set Stateflow Model Explorer properties in M-script?

In Simulink, Block-properties / handles can be viewed and set using the 'get_param' and 'set_param' commands, respectively. I would please like to know how to do so for Stateflow data (Model Explorer) using matlab script (i.e. in m-file).

>> Example: I have a Model "TestModel.mdl" which has a SF_chart in deeper layers: "TestModel/SubSystem_1/MyChart" for which I need to Add Data;

Name: PRES_C

Scope: Parameter

Type: Double
