One file might appear in multiple locations (e.g. an image that is used to explain something in the documentation). People might want to change it and make that change appear in many of the locations the file is referenced.
Currently, they have to open the file application, search for `F123`, go to the "Attached" tab and adjust each and every document (e.g. wiki pages) referencing it.
It would be nice if this could be simplified.
E.g. by adding a "Replace" button to the "Attached" tab of a file (say `F123`). Pressing it blends in a typeahead field where one can select the new file (say `F321`) from all existing files or upload a new one. Additionally, it blends in checkboxes next to all references in the list. References I do not have permission to change would be greyed out. Upon pressing "OK", Phabricator would automatically edit all references (e.g. wiki pages, tasks, etc) and replace `F123` with `F321`.
