Mark subfolders of shared folders also as shared

Hallo,

i want a simple customization.

A shared folder is marked as shared with a special icon. I want that all subfolders of this folder are also marked with this shared icon.

I think this should be done within the file apps/files/js/filelist.js, but i am not sure.

Pls send me a message when you can do this task!

best,
