Hi, I’m creating a monorepo for multiple sites, I run multiple sites on local, and I want to change some menu URLs to local development URLs. For example

```sh
$ tree config
config/
  _default/
    menu.yaml
  development/
    menu.yaml

```

\_config/_default/menu.yaml_

```yaml
main:
  - name: Icons
    identifier: icons
    url: https://example.com/

  - name: Modules
    identifier: modules

  - name: Projects
    identifier: projects

```

_config/development/menu.yaml_

```yaml
main:
  - name: Icons
    identifier: icons
    url: http://localhost:13131/

```

I expect that Hugo will deeply merge those menus, but the `Modules` and `Projects` menus were gone, is it expected? Is there any way to avoid repeating all menus for development env?

Yes, array is not merged by Hugo.

Thanks for the reminding, I forgot this. I keep this open to see if there are any solution to achieve this.
