To allow an Admin to apply a newly purchased package to past, historical appointments. Retroactively redeem a package session for an already invoiced past visit either from the customer profile or via the appointment Calendar directly. For instance, find the appointment time slot (past, in session, or future appointment for the client), then select the newly purchased Package and click to redeem it for that visit.
This feature will allow business owners to more easily sell packages to clients who want to try a single service first, before committing to a whole package.
This feature is available on at least one other popular booking system, indicating this is a valued feature.
