Grid/Column settings for kirby-builder

Hello everyone,

I ask my self if it is possible to extend the kirby-builder with a Column function witch has visible impact in the back end.

Normally you would just add more Components with different columns, but I like the idea of customizing the representation without adding a new block.

I tried a couple variations like this. But I have no clue how to access the current builder Element with like a ‘this’ selector.

label: Row {{ column }} # This query works fine
tabs:
  content:
    label: Content
    fields:
      pagebuilder:
        label: Input
        type: builder
        columns: {{ column }} # This query doesn't works
        fieldsets:
          section.content: sections/content
  columns:
    label: Columns
    fields:
      column: # Customize the amount of columns
        label: Column Count
        type: number
        default: '1'
        required: true

I would be glad if anyone have an idea. Thanks!
