Conditional actions and Auth / Capture

Alternatively, would it be possible to alter the module so that the payment is entered when the transaction is authorized rather than authenticated?

Ok, so I've come up with a really ugly hack - move line 714:

<?php
function uc_protx_vsp_direct_3DSecure_callback() {
...
  if ($result['success'] == TRUE) {
  //  uc_payment_enter($order->order_id, 'credit', $order->order_total, $order->uid, '', $result['comment']);
    $_SESSION['do_complete'] = TRUE;
    $redirect = 'cart/checkout/complete';
  }
...
}
?>

to line 1025:

<?php
function uc_protx_vsp_direct_auth_form_submit($form, &$form_state) {
...
  if ( $result['success'] ) {
    uc_payment_enter($order->order_id, 'credit', $order->order_total, $order->uid, '', $result['comment']);
    drupal_set_message(t('The transaction was succesfully authorised by the acquiring bank.'));
    uc_order_comment_save($order_id, $user->uid, $result['comment']);
 }
...
}
?>

Which only works if 3D-Secure is enabled, as the Ubercart CC module has its own call to uc_payment_enter().
This could be solved if the option to authorize and then capture were enabled in the payment gateway config page. But it's not. Any idea where I might start in order to get that enabled?
"Authorize / Capture" seems to be essentially the same as "Authenticate / Authorize".

Well... It would have made sense to at least tried the dev version before hacking away wouldn't it? I even made my own "capture custom amount" field. How silly of me.
