Admin rights

Hi,
In the groups config one can decide the rights for users.
At Events you can limit the number of tickets a subscriber can book/purchase. Thats a great option! But we need that admin-users are not limited to what the public users are allowed to due to group-booking with special agreements.
So, we would like that in the groups-config one can allow to override the events setting for number of tickets in one booking.
At the current moment there is no default option that you can use in order to limit the number of tickets a user can book on an individual registration based on the user group.
