Simple OrangeHRM customization

Hi all, We have OrangeHRM website (OrangeHRM 3.1.1). We need to add some customization to the attendance page. currently, adding attendance is done one by one. we need to add attendance for all registered employee in single page. Under Time menu, then Attendance submenu item, by click Employee Records, Choosing 'All' for Employee name, and today date, you will get all registered employees. This fine now. what we want is: - Ability to add attendance check for all registered employee (In/Out) in a single page. - ability to import the attendance time sheet from: csv, excel, text. - Ability to show full report for attendance for all employees - Ability to export the report to : text, excel, csv Regards, Ahmad
