I see. I believe the commands listed in the command palette are those offered by the build system. variants As you can't have multiple build systems specified per project (I think), I don't think it's possible to use the native build system to achieve what you want. That being said, I believe the build system are just a series of arguments passed to the "exec" command in Default/exec.py. So you can probably write your own plugin, perhaps wrapping the exec command, and add your own entries to a Default.sublime-commands file, which will then be added to the command palette. Actually, if you are just modifying the arguments to the exec call, you need a plugin, just specify the appropriate values as args in the Default.sublime-commands file.
