pageLayouts for multiple folders inside folder

How to achieve with panini to put specific layout for specific pages/folders.
For now i achieved to point as in documentation provided folder blog to blog layout. But panini does not goes deeper and points layout to other folders inside folders. How to achieve that?

It goes something like this but not successful
```
pageLayouts: {
'product': 'product',
'product/folder2/': 'product',
'product/folder3/': 'product',
'kontakt': 'kontakt'
}
```
folder2 and folder3 are pointed to defauly layout rather not to product layout
