folder.jpg not default folder thumbnail anymore

I've been using this great tool for quite some time now.
I've just been starting to use xbmc/kodi to access my serviio sources again.
I've noticed that something has changed in serviio.
I used to have specific folder.jpg files in all my video folders.
It seems the current version doesn't display them anymore. It uses the first picture it finds in the directory:
Example:
folder: Spiderman
files:
spiderman1.jpg
spiderman1.mkv
spiderman2.jpg
spiderman2.mkv
spiderman3.jpg
spiderman3.mkv
folder.jpg
Is it possible to add this feature back into serviio?
