Allow resource files to keep their original filename when uploading new copies

When you upload a file that already exists in the Global Resources area it amends the new filename with a '(1)'. Can it keep the same filename as previously used?

I've updated a resource document and now also need to update my help guides that were pointing to the document because the filename has changed. I needed it to remain the same.

I tried deleting all instances and uploading again with the original filename but it seems to have cached the file and won't open the most up-to-date copy.
