currently if I chose to set something like

options:
  find_existing_by: ['foo', 'bar', 'baz']

I have to provide all three keys even if I decide that one of the keys can be blank.

so instead of

records:
  - sprig_id: 1
    foo: bla
    bar: bla
    baz:

I would love to keep it

records:
  - sprig_id: 1
    foo: bla
    bar: bla

I hope I described it somehow clear!? 😉
