Multiple files for handling messages

[ahmadshiddiq]

I have check every example on the repo for the solution, but sadly i can't found it.
Is that possible to handle the messages with multiple files? our case, we have several products. i think its good if we splitting the code into more spesific and individual folder.

we try to reach like this:

• messages
  • en
    • product1.json
    • product2.json
  • de
    • product1.json
    • product2.json
