Equivalent to calling the per-layer add endpoint for each layer individually. If a modeling option for a coverage option does not yet exist, it is created automatically. Idempotent — layers that already have the coverage option are unaffected. Returns the full modeling option state for the layer structure. ## OpenAPI ````yaml https://vision.dev.pingintel.com/api/schema/?format=json post /api/v1/submission/{pingid}/cat/modeling-options/layer-structures/{layer_structure_uuid}/add-coverage-options openapi: 3.0.3 info: title: Ping.Vision API version: v1.0 description: > ### Ping.Vision API This API provides convenient, efficient access to Ping Intel's data and services. It is designed to be used by developers and data scientists to integrate Ping Intel's capabilities into their applications. Once SSO is set up with your organization, you can create an Organization or Personal API key at https://auth.pingintel.com/org. Please see the Python client library [pingintel-api](https://pypi.org/project/pingintel-api/) for commandline tools and programmatic access, and you can refer to the following documentation for details on interacting with the system via the HTTP API. contact: email: support@pingintel.com name: Ping Intel url: https://www.pingintel.com servers: - url: https://vision.pingintel.com description: Ping.Vision API - url: https://vision.staging.pingintel.com description: Ping.Vision API (staging) security: [] tags: - name: Create Submission description: The Create Submission API allows you to add new data into the system. - name: Update Submission description: >- The Update Submission API provides various endpoints to update, modify, or act upon existing submissions. - name: Get Submission Data description: '' - name: User Memberships description: >- The User Memberships API allows you to add, remove, and change the role of users in different teams, divisions, or companies. - name: Miscellaneous description: '' paths: /api/v1/submission/{pingid}/cat/modeling-options/layer-structures/{layer_structure_uuid}/add-coverage-options: post: tags: - CAT Modeling summary: Modeling Option - Add Layer Structure description: >- Associates one or more coverage options with **every layer** in the given layer structure.
