Is it possible, using YAML anchors, to define variables that you pass to the script

[Etienne Noel]

I want to us YAML anchors but in the script of my anchor, I need to pass a variable of the version that I push to NPM. Is there a way to pass or define a variable that will be used in the YAML anchor?

Here's what I'm trying to achieve

definitions:
  steps:
    - step: &build
        name: build
        script: 
          - npm version $VERSION_NUMBER

pipelines:
  branches:
    master:
      - step: *build
        VERSION_NUMBER = 1.0.0 # I don't know how to do this
  default:
    - step: *build
      VERSION_NUMBER = $BITBUCKET_BUILD_NUMBER-$BITBUCKET_BRANCH # I don't know how to do this

@Etienne Noel variables are not shared through artifacts, but you can put this string to text file and user VERSION_NUMBER: $(cat  version.txt)
