Additional options: if you bought the ticket without but you want

[gBaylaender]

If I buy a ticket without "Additional Option" and after a while, I want to buy it I cannot. Please allow the customer to buy after purchasing the ticket an additional option.

Why do I want to buy an additional option after I bought the ticket?

• Because the additional option was not available when I bought the ticket (e.g. Early Bird)
• I was thinking I don't need it
