Is there a feature/option of the AIX client that allows for multiple
restores of the same named file, automatically renaming the restored file
if it exists ?

We have a situation where someone deleted their e-mail and want to restore
from a backup. We keep 15 copies. They don't know which of the 15 to
restore, so they want all of them restored, giving them unique names (i.e.
.001, .002, .003, etc).
