I am currently programming a Soundboard. For that I would need to store the usergiven name of the sound, its path and a hotkey assigned to it. I also want the user to be able to add sounds whenever they like.

In a YAML document it would look something like this:

```
sounds:
    sound1:
        path: ...
        name: ...
        hotkey: ...
    sound2:
        path: ...
        name: ...
        hotkey: ...

```

Sadly I haven't found an easy way to append keys (sound3, sound4...) to a yaml like this.
Is there an easy way to accomplish my goal?
