[Question] Always returning an array from `az resource show`?

The following command returns a single resource object
```sh
az resource show --ids {id_1}
```

The following command returns an array containing multiple resource objects
```sh
az resource show --ids {id_1} {id_2}
```

Is there an argument I can use to ensure that an array is returned, regardless of the number of ids supplied? I was wondering if it's possible with the `--query` flag, but I'm not familiar enough with JMESPath and couldn't spot anything obvious.
