Webform: request submitted values in all page breaks

Question

I have multiple page breaks in a webform. Can I get all the values submitted in all previous page break? Actually I can get only the values for one previous page break(the last one submitted).

For example if i'm in the page break 4 only can request the values submitted in page break 3 not in all the previous (2 and 1). The other values are not present.

I'm using the hook_form_alter.

Getting the info from $form_state["input"]["submitted"]

    function custom_module_form_alter(&$form, &$form_state, $form_id) {    
      if(substr($form_id,0,20 ) == 'webform_client_form_') {   
        dsm($form_state["input"]["submitted"]);
        //Only info from one page break(previous)
      } 
    }

You can retrieve submitted values across all pages from $form_state['storage']['submitted'].

Note that this represents values from past pages and not the current page. Here is the code I use to get them all (past & current) page values into a single array:

$values = _webform_client_form_submit_flatten($node, $form_state['values']['submitted']);
$values += $form_state['storage']['submitted'];
