support prompts from array with async factory function and prev answers access

[GiladShoham]

Hi,
It will be awesome if the prompts(array) will support async factories function in the array.
Let's take the following example:

async function fetchRestaurantMenu(restaurantName){
// Do some query to DB or http request (async function)
// Will return an array of strings
}
function buildOrderFromRestaurantQuestion(restaurantName) {
  const menu = fetchRestaurantMenu(restaurantName)
  return {
    type: 'list',
    name: 'orderOption',
    message: 'select a dish',
    choices: menu
  };
}

const answers = await inquirer.prompt([buildOrderFromRestaurantQuestion('myRestaurant]);

It will be even better if during the prompt array I will have access to previous answers.
Then I can do something like this (assume functions from previous exists)

// A function used a previous answer to build an order from restaurant question
function buildOrderFromRestaurantQuestionWrapper(answerPropName) {
  // Access somehow to previousAnswers, there might need to be another function to get it
  // it's just a simplified example.
  const restaurantName = previousAnswers[answerPropName]
  return buildOrderFromRestaurantQuestion(restaurantName)
}
const selectRestaurantQ = {
    type: 'list',
    name: 'restaurantName',
    message: 'select a restaurant',
    choices: ['restaurant1', 'restaurant2', 'restaurant3']
  };

const answers = await inquirer.prompt([selectRestaurantQ, buildOrderFromRestaurantQuestionWrapper('restaurantName]);

I know I can achieve this functionality by explicitly calling inquirer.prompt (already done it and it works).
But this way (using the array form) it will be much more elegant.
