Using XILINX XPS with Microblaze - quickest way to program the fpga

I'm designing a micro controller based around the microblaze microprocessor on a xilinx fpga. Most of the hardware setup is done. All I'm updating at this point is the c code to be run on the microblaze. Is there a way in XPS to not have to rebuild the entire project, just the c code portion. It takes around 20 minutes to rebuild the entire project - would be nice if i didn't have to. Thanks.

Solution

Right click on the top-level C file. The option is there.
