Hello,
Yes, we already talked about that subject by email.
While I understand a part of your request, it is unfortunately incomplete since the "specify file location" could allow to point local files in the server ; thus only remove the "upload" is not really a full and complete solution.

By the way, do not send me private message, use the "contact us" form instead.
