Is there a way to set something up to allow guests to purchase the add-on surcharge options after they complete their initial booking? Say we offered a birthday cake, and they didn't buy it when they booked, but then decided it would be easier to have us provide it. Is there a way to set up a page, or an email with the options, to ask them one more time before they check in if they want any of the options?
Not at present. It is planned to be added in the future.
