We often had clients submitting lots of documents using the single upload, when infact they should have used the multiple one.

Currently we need to download the PDF (with multiple bills), archive it, then reupload again. If you have to do this for lots of items, its tedious and you need to be careful you don't miss any reuploads. It would be great to simply have a button that will resubmit the document for upload, but as multiple.
