When deploying updates from dev/test to stage/prod, it currently updates the whole solution. It would be a great feature to be able to select, e.g., which apps should be deployed. If there is a critical change in a single app that needs to be published for production immediately, it should be possible to only deploy these changes (the single app) and not all other apps that might not be ready for production.
Putting this out there as a feature request and hoping to see this in the future
