override the global delay setting within on command flow
Dear developer,

great work! One question. Is it possible to override the global delay setting within on command flow ?
somehow like this:
```
{
                            "name": "Bild in Bild",
                            **"delay": 2000,**
                            "command": [
                                "KEY_PIP_ONOFF",
                                "KEY_ENTER",
                                "KEY_RETURN"
                            ]
                        },
```

Thank you!
Thomas
