New Disney Tix Reservation No from Virgin Hols?

[mikeishere]

Ok so I’ve just rebooked / amended our holiday with Virgin Holidays as we where originally staying 14 nights in WDW but now we staying 11 nights in WDW and 3 nights on site at Universal but to do this VH are going to give me a new Disney Ticket reservation number. However I already booked in our theme park days ( as Disney now require) under the original Disney Tix reservation number given by Virgin on the ‘My Disney Experience app’ but now I’m going to get a new tix reservation number for amended booking how do I add the new Ticket Reservation No, onto my Disney Experience App under my name and overwrite the previous stuff on the app that was under my name and the ‘My plans etc bit’ so I can book my theme park days?
