How to structure navigation group items not only in the sidebar, but also the folder structure?

I was looking at the folder structure of the filament demo app, i saw that the Resources, Cluster folders has Shop and Blog folders to organize files. I downloaded and setup the demo app to add another subfolder to resource structure

- Resources\
  - Blog
  - Shop
  - Tasks

- Resources\
  - Blog
  - Shop
  - Tasks

If i put the TaskResource.php file in Tasks it doesnt load, even tho i have specified the navigationGroup, but if i put the file inside Filament\Resources folder it loads fine. My concern is how to structure my code like that into subfolders for each group.
