How can I tell Simulink Embedded Coder to get its variable names from my signal names, not the source block names?

I am generating C code from a Simulink model using Simulink Embedded Coder with the ERT target. I can see that the variable names generated in the code are formatted according to the Configuration Parameters under the Code Generation/Symbols pane. For example, I am using $N$M for my local temporary variables. In the simplified cases, the mangle is unnecessary and the variable name is just the value of $N, "Name of object being identified."

If I have two signals, a and b entering a Sum block and producing a signal named c, the signal emerging from the Sum block corresponds to a generated variable named Sum. But in my mental model, signals are the variables and blocks are the functions/operations. So I would like the variable to be named c, not Sum.

How can I tell Simulink to inherit its variable names from the signal names, not the block names?

I am using MATLAB R2015a (64-bit) and Windows 7. I set up mex to use the Microsoft Visual C++ 2010 (C) compiler.
