title: Using one YAML definition for the same column as it moves through models
body: <p>I have some model YAML:</p>
  <pre><code>version: 2
  
  models:
    - name: my_model
  
      columns:
        - name: foo
          description: My bestest column
  </code></pre>
  <p>...If I make other models which inherit from this one, is there any way to refer back to this column definition when documentation is generated, or do I need to copy-paste the column definition for each model in which the column appears?</p>
  <p>In other words, is there a way of defining a column only once to make edits and updates easier.</p>
  <p>Cheers,</p>
