Gift It - add another email

I am buying a copy that I can used both at home and at work - I can only sit in one seat.
I would also like to gift a copy to someone else, Ideally when I buy that it would have their email in the pay now section.
Where my email is the one where the copy of the bill goes to, and if I was buying it for my team I could add their names in. I just one the one invoice to expense.
thanks
