I have created an application for a TI F28035 microcontroller in Simulink using the TI C2000 hardware add-on. Everything works just fine. However, I was wondering if there was a way to insert custom lines of c code into the auto-generated code. I'm not talking about S functions or ceval calls or using the custom code portion of the Model Parameters. I'm talking about a simple block that lets you enter some simple lines of c code that when built will just plop those lines of code into the built code. Does anything like that exist?

In your version of Simulink, check Simulink Coder, Custom Code, Model Source block. It allows to add source code at either Top or Bottom of the model source code.

It doesn't do me any good to just add code at the top or bottom of the source code. I need it to be called by an external trigger. Ideally I would have a "custom code" block (that doesn't seem to exist currently) that I would place in a triggered subsystem.

In that case, use a Stateflow chart inside a triggered subsystem. You can pretty much write any manual code inside the Stateflow chart.

I'm not exactly sure what you mean.
The custom code I need inserted into the generated code looks like this. I tried just copying this into a stateflow state, but I get all sorts of errors obviously.
Uint16 *p_id = (Uint16 *)0x0006CD;
*p_id = 0x00FF;
Uint32 *p_data = (Uint32 *)0x0006CE;
*p_data = 0xFFFFFFFF;
void (*foo)(void) = (void (*)(void))0x4E9867;
foo();

Only way I know of is to create in-lined s-function. For Simulation, s-function would have no inputs, no outputs and therefore do nothing. For code generation, the TLC code for the s-function could emit the above code.
