If you edit a post, you can add a new attachment. Add the link to the old one in the post text, then check the "I want to preview my post and/or attach a file" option. Choose a new file for an attachment and finalize the edit. The "attachment" link at the top of the post will now point to the new attachment, but the old attachment will still work fine from the link you inserted into the post body. This will avoid making a ton of posts in a row for multiple attachments.
