List management for Vouchers and Coupons

we have quite some coupons now (also vouchers), and I feel like it would be handy to be able to sort them at least alphabetically, or mark favorites that appear on top of the list. It works as it is, but I think it could benefit from some UX improvements in regards to list management... Being able to sort alphabetically would already help - we could then just create custom sorting by naming the items accordingly...
