When I use the create voucher option, selecting all the bookings in my itinerary, the order the vouchers are displayed seems a bit random at times, and if I have several bookings with a same supplier, they will all display on the same page, even if they are on different dates (this ties in with the fact that we can no longer ungroup multiple bookings made with a single suppliers on separate dates within a single itinerary).
It would make it much easier to read for our clients if the vouchers simply display in chronological order of the services booked.
