payload validation for routes that have multiple method arguments

Is there a way to handle `payload` validation for routes that have multiple `method` arguments?

``` js
server.route({
    method: [ 'GET', 'POST' ],
    config: {
        validate: {
            payload: {
                value: Joi.string().required()
            } 
        }
    }
});
```

I get the following error:
`Cannot validate HEAD or GET requests`

v8.8.0
