Waypoint workspaces with Google Cloud Run

I’m trying to run through the waypoint tutorials to deploy using the google cloud run plugin, and leverage waypoint workspaces to configure “preview” feature branch builds and per developer environment workspaces.

When I try deploying to a workspace e.g.

$ waypoint up -workspace=dev

It appears to deploy / release to a single Google Cloud Run service, I was under the impression that with the -workspace=dev flag that it would create a separate Google Cloud run service for that workspace?

Is that not the intended behavior of the google cloud run plugin, or am I missing some configuration?
