[Solved] Setting items on multiples config files

[eluser]Fribos[/eluser]
Hi, i'm loading 4 config files. Note than i'm using the second parameter to avoid collisions.

Code:

$this->config->load('destacadas_izq', TRUE);
$this->config->load('destacadas_der', TRUE);
$this->config->load('titulares', TRUE);
$this->config->load('miniaturas', TRUE);

How can I set an item in this case? The user-guide says

Code:

$this->config->set_item('item_name', 'item_value');

But what about if I need reference an especific file ?

Thanks !
