Create a subfolder after creating a new post

[Mrahmani71]

Hi, is it possible to create a nested folder like images after creating a new post?

For example:
├─ post-01
│ ├─ images
│ └─ index.mdx

You can do some things with the paths: https://keystatic.com/docs/content-organisation#collections
But I don't know if it works with the images in the same folder.
