Using sub-folders for local files location

[khboo]

Hello,

I am configuring to use the local file system for the image files location: FilesystemSource.BasicLookupStrategy.path_prefix

I need to create sub-folders under 'path_prefix' to distribute the image files appropriately.
The problem is when I need to access the file under a subfolder, there seems to be no way of specifying the location.

e.g., http://localhost:8182/iiif/3/image.tif/0,0,200,200/max/0/default.jpg
image.tif is located in 'path_prefix.'
If I placed the file under 'path_prefix/group/version/image.tif, how can I specify the file with its location from the example path above?

Thanks.

I think I found a solution after reading through the doc:
"It's also possible to include a partial path in the identifier using URL-encoded slashes (%2F) as path separators. subdirectory%2Fimage.jpg in the URL would then resolve to /usr/local/images/subdirectory/image.jpg."

I was looking for a way of doing mappings for finding a file. It seems I may be able to do this using 'delegation' even though I have not looked into it yet.
e.g.,
a.jpg -> sub1/a.jpg
b.jpg -> sub2/b.jpg
