Change function to arrow function Follow

Hello 

When a function does not exist and it is called in the source code, there is a create function <insert name> that generate this code:

function $functionName$ ( $parameterNames$ ) {
$content$
}

Is it possible to tweak this behavior to generate an arrow function instead? Like this:

const $functionName$ = ( $parameterNames$ ) => {
$content$
};

Thank you
