Replacing attachment, and keeping same ID/Link

[Rop]

Like Honda, I too am looking for a mod that will allow the forum members to update attachments. The forum is set up to allow members to edit their posts (and thus attachments) for a limited time only, this is to promote thread continuity. Once the edit time expires the users can only delete attachments. However, there often is a need to update, for example, a spreadsheet with a newer version. Currently this can't be done, once the edit time expires the attachment can only be deleted, not updated.

Is there anything out there, a mod, that'll do what I'm looking for? For example, it would be great if members could use the attachment manager in their User CP to choose between deleting and updating.

Thanks!
