Visibility of Leaves Calender to All, but Leaves Capacity to self only

Hi,
We would like to show everyone the leaves calendar. But I dont want employees to see each other's earned leaves, it is more personel and "earned" value from the company.
I achieved it by changing a few lines in php. Some additional access restrictions for the HR modules will be great.

My solution is to edit dashboardEmployeeManager.php as:
//line 34
  require_once('../tool/projeqtor-hr.php');

 //line 65
  //$employeeList = getUserVisibleResourcesList(true, "List",'',     false, true, true,  true,true);
  $employeeList = getUserVisibleResourcesList(true, "List",'', true,  true, false, true,true);

//LINE 823
                                           foreach($employeeListRequest as $id => $name) {
                                                //errorLog("id:".$id." name:".$name." user-name:".$user->name." user-id:".$user->id);
                                                if ( isLeavesManager(getSessionUser()->id) )
                                                {                                                    
                                                  //  errorLog("user is manager of leaves");
                                                }
                                                else if ($id != $user->id )
                                                {
                                                  //  errorLog("user is NOT manager of leaves");
                                                    continue;
                                                }
   

//AND also give list of resources access to all employees to get a full list of users in the organization.

Best regards
