Create source maps for multiple files with expand

[rmbaad]

I have this part of config:

closureCompiler: {
    options: {
        compilerFile: 'system/utils/compiler.jar',
        checkModified: true
    },
    compilerOpts: {
        compilation_level: 'SIMPLE_OPTIMIZATIONS',
        warning_level: 'verbose',
        summary_detail_level: 3
    },
    minify: {
        files: [{
            expand: true,
            cwd: 'public/3/js/sources',
            src: '*.js',
            dest: 'public/3/js/min',
            ext: '.min.js'
        }]
    }
}

Can I create souce maps a similar way?
Now I have in public/3/js/sources:
profile.js
support.js
offer.js

Ant this files minified to public/3/js/min:
profile.min.js
support.min.js
offer.min.js

And I want to have in public/3/js/min too:
profile.min.js.map
support.min.js.map
offer.min.js.map

I don't understand how to do it. Can you help me?)
