Reminder Alert Notification

Hello
please can you consider to add Reminder Alert Sound where by customer chooses the time and date that he want to be reminded for his trip with sound alert for some seconds on his mobile phone also
when a ticket is sent in a pdf format it should also send another pdf with just QR code and Ticket PIN and company name so that it is only qrcode info will display when ticket is opened in mobile phone so that it will be very easy to scan the code from customer phone
