[Feature Request] Multiple local sources or having the possibility to add more levels in the data structure of local folder

[campana-giuseppe]

What feature should be added to Tachidesk?

I would add having the possibility to add more local sources giving the path or more simple to have the possibility of being able to add a layer to the data structure in use at the moment so that the content can be organised on the machine.
To explain better, this would be the situation locally in the folder "local" of Tachidesk:

../local/
  - group1/
      Manga title/
        Chapter 01 - Prologue/
          page01.png
          page02.png
          page03.png
          ...
-   group2/
      Manga title/
        Chapter 01 - Prologue/
          page01.png
          page02.png
          page03.png
          ...
-   group3/
      Manga title/
        Chapter 01 - Prologue/
          page01.png
          page02.png
          page03.png
          ...

Why/Project's Benefit/Existing Problem

Using Tachidesk on server it may not be good to have only one folder as source and you might need more folders to organise the resources. This is because it is fine that on the application then it is possible to categorise, but those using it on a server might be able to use the content simultaneously on other services such as self-hosted cloud and then in general also on the machine itself it might be useful to have the resources categorised.
