Writing the same config for different targets in Grunt - coffeescript

Question

I have a task with different targets on my Gruntfile, and all targets contain exactly the same fields changing just the name. Is it possible to create these targets programmatically, passing just the list of targets?
My goal is to create a list of submodules installed and create a task with a target for each submodule. To be specific, the task is not mine, I'm trying to create targets for a coffee task to compile some files, but I will also need to do the same with handlebars templates later on.
I've tried creating a generic target and passing the submodule name like this:
grunt.initConfig(
task: {
target: {
expand: true,
flatten: true,
cwd: "<%= AppModulesPaths[grunt.task.current.args[0]] %>" #"<%= frontend_src %>",
src: ["<%= AppModulesSources[grunt.task.current.args[0]]%>"],
dest: "<%= frontend_tmp %>",
rename: function(dest, src){
return dest + "<%= grunt.task.current.args[0] %>.js"
}
}
}
})
And then register a task array with task:target:targetname but it's complaining about args being undefined.
Is there a good way of doing this?

Of course, it's just plain JavaScript.
function config (targets) {
var result = {};
targets.forEach(function (target) {
result[target] = {
// target configuration here,
// optionally tailored to the target's name
};
});
return result;
}
Then, just use it
grunt.initConfig({
task: config(['target', 'target2', 'target3', 'targetN'])
});
