Generating voucher for add-ons?
We have a couple of bundle deals where a customer can purchase an inventory item (swim session) for a fixed time and date then add another 2 or 4 sessions for a later date at a discount (unspecified time and date at time of booking). This is currently an add-on in package only settings.
Whilst we can manage this manually at present it will be much easier if the user could get a voucher code or something so that they can come back to pick their later dates and times themselves. Is this possible? They won't know on first booking when they want the later dates. Or should we revert to a voucher only add-on for the value of the subsequent sessions?
