### Describe the feature you'd like to request

Add the ability to pull other Amplify backend environments from the cloud without also specifying the Amplify App ID.

- in projects where we've chosen NOT to modify the backend, we are able to pull the new environment from the cloud with:
```shell
amplify pull --appId --envName main
# ...
amplify pull --envName next
```
- in projects where we've chosen to modify the backend, we are unable to pull the new environment from the cloud without also specifying the App ID `amplify pull --appId --envName `

### When choosing to modify the backend

```console
> amplify pull --appId --envName main
