I am using Simulink Embedded coder package for Texas Instruments(TI) C2000. But there is no DAC block for the processor I have when it actually has a DAC on the hardware. Is there any way to create a new block for my TI board?

I am using a development board from Texas Instruments (Delfino TMS320F28377S) which is supported by Simulink Embedded coder. But in Simulink, there is no blocks to make use of the DAC port available in the board. Is there any way to make a DAC block in Simulink for my board? I also don't see any communication blocks (SPI) for the same. I am using Matlab 2015b with Simulink support for TI's C2000 processors.
