Well i haven't done what your talking about before, but from looking at the upload.php file in the libraries folder there does not seem to be a way to do this, i would suggest either writing in a way to do it somewhere about line 186 - 192:
// Set the uploaded data as class variables
$this->file_temp = $_FILES[$field]['tmp_name'];
$this->file_name = $_FILES[$field]['name'];
$this->file_size = $_FILES[$field]['size'];
$this->file_type = preg_replace("/^(.+?);.*$/", "\\1", $_FILES[$field]['type']);
$this->file_type = strtolower($this->file_type);
$this->file_ext = $this->get_extension($_FILES[$field]['name']);
Specifically:
$this->file_name = $_FILES[$field]['name'];
