How to make more readable and shorter a karate scenario

I'm new in Karate Framework. I would like to write a scenario like here:

version 1 :
Background:
        * url 'someURL' 
        * def user1 = {id:'123', name:'Bill'}

Given I have a user with id '123'
When I create a new user with the same id
Then I should get a response 'user with this id already exists'

But in Karate I have to write it like here:

version 2 : 
Background:
    * url 'someURL' 
    * def user1 = {id:'123', name:'Bill'}

Given request user1
When method post
Then status 201
Given path response.id
When method get
Then response == {id:'123', name:'Bill'}

    * def idUser1 = response.id

Given request == {id: idUser1, name: 'Gary'}
When method post
Then response == {code: 400, message: 'user with this id already exists'}

How I can get the first version with Karate framework? where I have to detail the 3 lines? ex: Given I have a user with id '123' and behind (I don't know where and how) detail it with

"Given request user1
When method post
Then status 201
Given path response.id
When method get"
Then response == {id:'123', name:'Bill'} etc.
