Please can something be implemented to allow us to offer a discount for group bookings on events.

For instance, we want to encourage bookings on a fundraising event by offering a cheaper per person price for groups of 5+. Currently there isn't a good way to do this - we could set a group booking option, but this would be fixed size, and so if someone wants to register 6 people then they have to pay full price for the extra person. We could set up two registration types without a fixed size and name them to show that the discounted version is only for bookings of 5+ people,  but we get into a sticky situation if someone makes a mistake and registers two people on the discounted price.

The simplest fix I can think of would be to allow us to set a minimum and maximum booking size instead of just a maximum, and have these minimums and maximums be attached to each booking type, rather than universal for the event registration form.
