STM32F4 how to change build action

Hi,

I'm new with the STM32F4 discovery board. I want to try step number 3 http://www.mathworks.com/help/supportpkg/stmicroelectronicsstm32f4discovery/examples/getting-started-with-stm32f4-discovery-support-package.html where it says "Change Build action to Build to generate only hex file, stm32f4discovery_pb_led.hex. In order to set Build action, follow the steps below:" but no such "Build Option" group exists. So i don't know how to download my code to the STM32F4 board. The button "Build Model" just builds it. Is there any other way to download automatically the code to the board using MATLAB?

Thanks in advance.
