In ST2, can I bind a specific build system to a key?

I have JSLint set as the build system for .js files, so that it invokes JSLint for the current JSLint file.

I’d like to have Command+Shift+B invoke a different JSLint command that runs on all the files in the project.

I know I can do:

{ "keys": "super+shift+b"], "command": "exec", "args" : ] }

But I’m not able to access the $project_path variables, etc.

Does the “build” command take any arguments? Something like the following (which does not work) would be cool:

{ "keys": "super+shift+b"], "command": "build", "args" :  "JSLint All"] }

Any ideas?

Thanks!
