Currently, if a new client doesn't use their referral code on their first appointment's order (for example, if there's a separate new client offer they want to use first), the code doesn't appear as usable on a later order, since it's only fixed to the first appointment.
Instead, the discount must be manually added but then doesn't apply towards referral program reporting.

It would be great to be able to have that offer code still available in the dropdown for that client as long as they have not yet used it.
