[galaxy-dev] Only use filepaths and "Copy data into Galaxy?"

Hello everybody, i've got one galaxy server running. The ressource on the wiki are very useful for that purpose, thank you. I've got one question regarding data library when using "upload files from filesystem paths". There is a checkbox, unchecked by default, which prevent file upload into Galaxy. Is there a way to activate this checkbox by default, or to totally remove it on a per library basis ? I'm afraid of data libraries admin forgetting to check this box :D Regards, Jean-Baptiste
