Yeah you can use preview/review apps via the `apps:clone` command[1]. It can be used in a pipeline to setup custom apps for code branches, allowing folks to stand up custom versions in CI for merge/pull requests[2]. If your deployment platform doesn't support this in some way, I would definitely recommend investigating it, as there is a _ton_ of stuff you can do with this.
