Changing subfolder structure

I hope I'm making sense to what I wanted to do.
Let's say I got 16 files named A1, A2, A3, A4....B1-B4, C1-C4 and D1-D4.
Currently they are under the folder structure like this:
- Main Folder
- Folder A
- A1
- A2
- A3
- A4
- Folder B
- B1
- B2.......
How to I use Hazel to switch from the above structure to below, and vice versa?
- Main Folder
- Folder 1
- A1
- B1
- C1
- D1
- Folder 2
- A2
- B2.......
Cheers,
Chris
