Deployment Pipelines for Dataflows with Parameterization for Linked Entities

We need the ability to have real DTAP for dataflows that have linked entities.

For each stage in my DTAP process I have a pair of ingestion and transform dataflow workspaces. The transform dataflow uses linked entities from the ingestion dataflow workspace. Since the linked entities cannot be edited in the transform dataflow workspace there is no way to parameterize the link. What I'd like is the ability to point the linked entity to the correct version of the ingestion entity. This way, when I promote the code from dev to test, I can change the linked entity via the parameter.

Since the linked entities are incorporated into the JSON file for an entity, if I were to promote a set of changes to the entity dataflow from dev to test by importing the JSON, it would be pointing to the dev version of the ingestion entities.

Ideally, I could create a Power Query parameter that could set up the linked entities to point to the correct ingestion workspace entities based on stage in the DTAP pipeline. Then the code I write in dev could migrate through the process without significant rework and potential for defects from manual changes to the files.
