Nth option as default, in 'default', in 'radio' field?

When querying the options of a radio field, is it possible to set an ‘Nth’ option as default ?

      defaultsize:
        label: Default size
        type: radio
        default: 1
        options: query
        columns: 6
        query: 
          fetch: page.sizes.toStructure
          text: "{{ structureItem.size }}"
          value: "{{ structureItem.size }}"

Doesn’t look like it… :woman_shrugging:

So sad…
