When I want to relinquish ownership of a file(s) and uncheck this box, I often don't want to apply it to all the files, but because there is not other method at this point but to go into the vault and regain ownership of the files that you want. In this case I have a factory file that I am checking in certain members and want to release ownership of, but not the parent factory file. I would like to see this option be able to select which files to apply this to.
