Create children text styles
Hello!! Thanks for this amazing tool!

I am trying to nest different text styles to have, for example, different alignments under the same style.

```
Body: {
      fontSize: 16,
      fontFamily: fontFamilies.fontFamily1,
      fontWeight: fontWeights.bold,
      lineHeight: 22,
      color: '#ccc',
        center: {
          textAlign: 'center',
        },
        right: {
          textAlign: 'right',
        },
      },
```
We are planning to create our text styles libraries with the plugin and we need to have different children for alignment, colors and weights under the same parent. Is this possible in any way?

Thank you so much!!
