Hello,

I see [here](https://discuss.elastic.co/t/api-for-creating-scripted-fields/139236) the correct way to upload a new scripted field to an index pattern in Kibana.

If I want to update a scripted field, can I append to the index pattern `attributes.field`? Will this overwrite the current scripted field with the same name or do I need to parse through the JSON array, pull out the field I care about, update the `script` section of the field, reserialize and post to the update API?

If you are on a recent version of Kibana you could use runtime fields and the specialized api for this use case: [Upsert runtime field API | Kibana Guide [8.1] | Elastic](https://www.elastic.co/guide/en/kibana/current/data-views-runtime-field-api-upsert.html)

What versions of Kibana support runtime fields?
