Versioned attachments?

Is it possible to have some sort of version control on RT attachments?
i.e. If someone opens a ticket with “foo.tgz” as an attachment, and
later in that ticket’s history, another “foo.tgz” is attached. RT
includes both attachments in the ticket, though they are dated.

Normally this is okay, but if we really only wanted to show the latest
instance of that particular attachment, is there any way to hide the
older ones?
