Custom errors to send custom status codes

I am trying to implement a validation chain, where some errors should return 400 (with a specific message) but some other should return 403 (with a specific message). I have found no neat way to do this, as I handle all validationResult(req) at the end of the validation chain. It would be cool to be able set like withStatus that gets attached to the results, or maybe even withCustom to add custom things to it. Or maybe there is an easier, more intuitive way?

Will try it when I get a chance, thanks.

.withMessage((value, { req }) => {
  return { ... }
})

Does this work?
