Not specifically, however in principle:
read/find
unset all keys/foreignkeys
call create
call saveAll
You'll find however that saveAll only goes one relation deep, so if
depending on the depth of your data you may find you need to save
related data in a loop, or create a semi-recursive duplicate logic.
e.g.
function duplicate($data) {
$this->save($data);
$data = Set::merge($data, $this->read());
$this->OtherModel->duplicate($data);
$this->OtherModel2->duplicate($data);
$this->OtherModel3->duplicate($data);
.etc..
}
