Create new Build Configurations

Hello,

I have a Nios II software project with several build configurations (besides Debug and Release) and want to build them all at once automatically.

In the Nios II Software Developers Handbook, the Altera Command Line Tools nios2-create-* and nios2-build-project are described. These tools could be useful for my application, but I also would like to create new build configurations. Is there another tool, procedure or method to create these build configurations from command line?
