Separate Tax lines

[DuFF1]

I'm charging two (2) tax to my customer but I want them to be on separate line.

 

Example:

 

Now:

Tax1 + Tax2 = 3.94

 

I Want:

Tax1: 2.94$

Tax2: 1.00$

 

I cannot figure out how to change theses lines in includes/modules/order_total/ot_tax.php

 

function process() {
 global $order, $currencies;

 reset($order->info['tax_groups']);
 while (list($key, $value) = each($order->info['tax_groups'])) {
if ($value > 0) {
  $this->output[] = array('title' => $key . ':',
						  'text' => $currencies->format($value, true, $order->info['currency'], $order->info['currency_value']),
						  'value' => $value);
}
 }
}
