If you're looking to update multiple cortex.yaml files at once, we recommend utilizing the Cortex API (https://docs.cortex.io/docs/api) over GitOps, Scaffolder, or UI Editing.
When working with mass updates, the Cortex CLI tool is also valuable, but requires yq installed (Mac users can run brew install yq). You can use the CLI to export entity YAMLs and organize them in a structured directory if using GitOps (.cortex/catalog for services and resources, .cortex/domains for domains, and .cortex/teams for team configurations).
