can a subsystem instance identify itself by a textual identifier known a priori ? Once Coder translated into 'C' or 'PLC" (ST) can the block still find its instance name?

I'm using both Embedded Coder and PLC Coder to translate models into a (Straton) PLC. I often have multiple instances of a subsystem that I'm generating code ('C' or 'ST') for. The subsystem may be private to the model or referenced from a library.

On the PLC embedded target, I need each instance of a subsystem to parse a textual resource file in order to customise its behaviour. I've been trying to discover how a block discovers its instance's textual name so that it can assign its internal settings based on the resource values in the block for its own instance.
