In GruntJS, is there any way to name a file generated by a task with the same name as the source file.

For example, if you wanted to compile all `.less` files to individual `.css` files, is there any way to do it like this:

```
files: {
    "css/<%= target-filename %>.css": ["less/*.less"]
}

```

where `<%= target-filename %>` is the value of `*` of that current `.less` file?
