RFI Numbering

Users are wanting to know the RFI number prior to publishing (while in draft) so they can name their attachments with the RFI number, but the number is not assigned until published which is too late to add attachements. Can we preivew the next number for them? Maybe we offer a "hold this number" options so that others don't publish over the top of them and they lose the number? If a number is held and the next form was going to be published it would be good to warn them "a number is being held by [user name] so this form will get the next number is sequence".

This feels like a very complex way to solve a simiple problem… There has to be a better way to allow attachement naming to match the form number.
