Hi Allegro33,
Thanks for posting this on our forums, I'm afraid as NewApollo already mentioned we're not able to do this kind of change here on our forums.
We can deal with mostly everything apart from package changes and cancellations 😊
I have a link here which has more info on how you can change your package - How to Change
Good luck and let us know how you get on!
Thanks,
Megan_L
