Included files ignored

Hi all,
congratulations for the fantastic software.
I have a question, if I configure in the server some “included file” these seem to be ignored by clients that have manually set their own paths, is a normal behavior? Is there a way to force “included files” even when a user has entered their paths?

No one have a reply?

There is another way to add a backup location to all clients, and make sure that they can not remove it, but only add other path?
Would be fine add it via scripts or command line.
