Files section keep lettercase in filenames

is it possible to disable filename sanitation (to lowercase and minus) for a files section like in k2?

I can’t find anything in the docs or in the source code that hints to such an option.

thanks @texnixe for verifying my suspicion.

a client of mine has some pdf shared for download file where preserving the filename could make sense. i explained to them why filenames in lowercase are considered best practice in the web.
