Is there any way to use more than one customAspectRatio preset?

Below is the code that defines one custom preset. But if you need more ( "Own preset 2", "Own preset 3") ? Or if you need to change the names of existing presets?

```
        cropViewController.customAspectRatio = CGSize(width: 4, height: 5)
        cropViewController.customAspectRatioName = "Own preset 1"
```
