Collins - Limit the total number of pre orders via booking type settings

The customer offers pre orders as a board for the whole table. Guests mistakenly order a menu for each person as there is not a setting in Collins to prevent this.
In the pre order settings in the booking type they need a setting to limit the maximum number of items that can be ordered.
The limit pre order items from % rules would work but a different rule would need to be set for each group size so this is not a practical solution given the number of different rules this would require.
