Feature Request: Gift Certificates for bookings & services, events & subscriptions

I was having this specific issue (I have been asking for Bookings Gift Cards since this time last year I reckon!) and my awesome Partner manager sent me this as a workaround in the meantime! https://wix.hubs.vidyard.com/watch/coEzQGZtaUPncC5MaFGUro

I am hoping to implement this myself tomorrow so fingers crossed!
