The source configurations of the Logs UI and Metrics UI are stored as saved object using Kibana's built-in mechanism. For administrative purposes (especially in infrastructure-as-code scenarios) it would be convenient to be able to export and re-import the source configurations via the Kibana saved object UI and API.

This can be enabled be enhancing the saved object definition slightly.
