I have had to replace a final return on occasion. My process is to delete the return from the portal and upload the replacement with the same file name. When I do that, the file that shows up in the portal has a number 2 next to the file name. I prefer not to have it numbered, and we have no way to change it. If I delete something from the portal, I want to be able to use the same name. Ideally, I'd like to replace the file so that it overwrites the original file as opposed to deleting the original and uploading the replacement to eliminate additional steps.
